"It is easy to learn C++,if you have the good knowledge of C".C++ language is basically an Object Oriented language. Therefore it is also called as Object Oriented Programming(OOP) . The difference between C and OOP is that-----
In C, program is divided into different functions.
In C++,it is divided into no. of objects.
There are some extra features in OOP. They are as follows :
1) Data hiding.
2) Encapsulation.
3) Inheritance.
4) Operator Overloading.
5) Polymorphism.
6) It includes all the featuers of C.
Hello…To C++ Programmers, Would you please tell about the Map of learning C++ LANGUAGE?
First of all read C++ basics like OOPS, then Charcter Sets, Keywords, Variable, Data Types. Then read about Classes and Objects, then try to solve simple questions then move to Conditonal statements(If-Else),then Switch, then Looping and so on

C++ Programmers i realllllly need ur help!!!?
if you can please do this program for me or guide me as to how to do this it would be MUCH appreciated. This is all i can do: (i can only find the remaining time of the same day, not of a specific date)
#include %26lt;iostream%26gt;
#include %26lt;string%26gt;
#include "ccc_time.cpp"
#include %26lt;cmath%26gt;
using namespace std;
int main ()
{
Time t;
int gethour, getmin, min, hour, remain;
gethour = (t.get_hours()%12)*60;
getmin = t.get_minutes();
cout%26lt;%26lt;"Enter the time that the Exam will begin (hh mm): "; cin%26gt;%26gt;hour%26gt;%26gt;min;
remain = abs((gethour + getmin) - ((hour*60) + min))
hour = remain/60;
min = remain%60;
cout%26lt;%26lt;"You still have "%26lt;%26lt;hour%26lt;%26lt;" hours and "%26lt;%26lt;min%26lt;%26lt; " minutes to prepare for the Exam.\n";
return 0;
}
Write a program that asks for the due date of the Midterm (hour, minutes). Then print the
number of minutes between the current time and the date of the midterm in the form “You still have XX
hours and YY minutes to prepare for the midterm.”

C Programmers, help me please...?
how can I count a certain letter or digit in a word?
let's say
MISSISSIPPI
1=M
4=I
4=S
2=P
it would me more appreciated if your answer would be string, array, etc.
C Programmers, help me please...?
char *mystring = "MISSISSIPPI";
int length = strlen(mystring);
int countletters(char str[])
{
int count = 0, k = 0;
while (str[k] != '\0')
{
if (str[k] == 'YOUR LETTER')
count++;
k++;
}
return count;
}
hope this will solve your issues

Reply:If you're looking for a specific character, do:
int CountCharacters(char *str, char find)
{
int count;
for (count=0; *str; str++ )
{
if ( *str == find )
count += 1;
}
return count;
}
Building on that (although definitely not especially efficient since it requires scanning the string for each letter), if you wanted output:
void CountCharacters(char *str)
{
char *find;
char *findPointer;
find = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
for ( findPointer = find; *findPointer; findPointer++ )
{
int count;
count = CountCharacters(str, *findPointer);
if ( count %26gt; 0 )
{
cout %26gt;%26gt; *findPointer %26gt;%26gt; "=" %26gt;%26gt; count %26gt;%26gt; "\r\n";

C programmers, have you seen this before?
I was comparing two floating point numbers to determine when to exit a loop. One floating point was set to 2 (float1). The other started at 1 (float2) and was incremented by 0.2. The loop was supposed to exit when the second floating point got to 2.2 (as in loop while(float2 %26lt;= float1), but it would always exit at 1.8. The only way I could fix it was to do a (fabs(float1 - float2) %26lt; 0.01), along with an or statement of float1 %26lt; float2.
I watched the numbers in the debugger, and it wasn't as if it said 2.00001 when it incremented to 2. Basically, it looked as if it was saying 2 is not equal to 2. I thought I was going insane!!! How could 2 not be equal to 2??? But I guess with floating points, there some issue with precision?
C programmers, have you seen this before?
Yes. This happens. Its a problem when you're dealing with floating point numbers. Like 1/3, which cannot be represented by a finite set of numbers (3.333....) floating point numbers have some variance.
Reply:Use abs(f1-f2) %26lt; epsilon(very small number) to compare them

I m a .NET programmer and i want 2 change a default error mesaage. how can I do it in C#?
You mean for ASP.NET I presume. You can either define the URL of the custom error at the page level using the Page directive's ErrorPage attribute, and/or you can define it at the web application level in Web.Config, using the defaultRedirect attribute of the customErrors element.

Seeking tips for becoming a good programmer. i'm just a beginner.How shall i start. i know basics of c++,Tips!
Different personalities are required. If you have good attention to details, that is extremely important in "embedded" software design (embedded systems are the small computers that are built into cars, aircraft, photocopiers and such). If you are good in math, then image processing or statistical analysis may be the best field. If you are good with people and planning, then there is a HUGE need for managers that understand software - you may not need to program a lot, but being able to help out in design and estimated is a large asset.
Write lots of software, learn how to debug. The skill of debugging is one of the most important skills that a programmer can learn, yet is often missing in programmers. This point cannot be overstressed.
There is far more to programming than banging away on a keyboard. Take time to design your software on paper. Make sure that the design "feels" right. THEN start to implement it. Starting off on the keyboard is almost a guaranteed recipe for disaster.
Learn how to test your software. Again, this is a skill that is lacking with many programmers. They will try a single test on their program, and call it done. This is not good enough, and once you are working, you don't want your customers to find YOUR bugs - that is not what your employer wants.
You should roughly spend 1/3, 1/3 and 1/3 of your time in design, coding and testing. Programmers often neglect the first and last parts of this.
Do not just chase the latest programming language - learn good programming practices that are portable from language to language.
Hope this helps!

Remember programming is about programming good (hacking), not about meetings, coaching or any other thing. It is an art, there is no such thing as engineering involved. (Please see Paul Graham on this department).
Then go see best practices and what's horrorful on the great "Code Complete".
Be defensive and pendatic about your code, which shouldn't mean not hearing critisisms.

1. Comments. Put comments in your work it helps you find what you are looking for easier. Be detailed enough. Gone are the days when space was an issue so comment to your hearts content.
2. Tab Order - Make sure when someone presses tab it goes to the next button or option and not to the other end of the application and back again. (Mostly for Forms)
3. Join mailing lists based on the language you are writing in. This will help give you an group or team approach to any problems you have.
4. There's no such thing as a stupid question, so don't be afraid to ask someone.
These are just basic ideas as to what I think could help you become a better programmer.

Is experience more important, when it comes to C++ and coding?
My husband has been a C++ programmer, he also knows linux, SQL, Java, running a pc virtual machine, pretty much everything there is to know about computers, this guy knows it. hes self taught, and is thinking about going to get his A.A, problem is, is spending 40 grand on a peice of paper worth it? is that what employers look for instead of his 5 years of experience and 13 years of coding? please tell me what you think.
Is experience more important, when it comes to C++ and coding?
His expirence seems flawless, and any employer will be looking for that. Allot of us out there have tons of knowlege about computers, but can't get jobs or careers, or even afford to go to college. His knowlege is very useful and he has several areas of expertiece. If he wants more, which most programmers, and coders do, then he should goto school and get it over with. He just might run into that certain employer that wants to see that $40,000.00 piece of paper. As long as he balances the thin line of Experience with education you can't go wrong.
Reply:I failed out of college and manage to keep getting jobs in the programming industry. If I can get into the interview, it's all downhill from there cause I know my stuff. Most places won't look at me though without it. It's there loss, although I will be getting my degree soon so I can increase my earning power and avoid being rejected by someone's bias against my lack of a degree.
The piece of paper really is worthless, most colleges don't even teach you enough to get out in the field programming, just the basics.
Reply:The "piece of paper" shows commitment, persistence and trainability. All good traits for a prospective employee. It shows an employer that someone was committed to a task and followed through.
Reply:Getting an associates degree in CS shouldn't cost that much. I got a 4 year degree (in Oklahoma) and my TOTAL tuition cost was $16,000.
Experience is gold, but a degree can get you in the door so that people will let you show off that experience.
Could he do online courses or get mondo-certifications: A+, C++, etc? A bunch of accrediations might also open doors.
Reply:As an alternative to a degree, he could instead take standardized tests offered by IEEE and similar professional organizations to get certified.
If he has only his experience, most software development forms won't be interested unless he can demonstrate his skills first.
Reply:Experience in the IT/computer programming field is very important. Almost every employer is looking for at the very least 1yr experience but usually they want 5+ years. Some companies will hire somone that has the equivilent amount of experince to a 4 year degree. It really depends on the employer.
Before he goes to get a degree, get on monster.com, carreerbuilder.com and look for programming jobs, apply to a few even if they are asking for a BS in computer science. You may also want to contact a potential employeer and ask if they except years of experience in leu of a degree.
Good luck!
Reply:Experience is important and it shows the difference between senior developers and junior developers. However, nowadays certification is the most important thing for the employer. Certification is like a proof of skill and expertise.

How do I pass parameters in C?
I'm a beginning C programmer, trying to write a simple little program. The goal is to find the cube of a number (i.e. 2 * 2 * 2=8), by using a self-made function and then passing the argument from the main function to the self-made function then having that number go back to the main function and print the result. Here's what I have:
#include %26lt;stdio.h%26gt;
int test(int first);
int main(void)
{
int number, cube;
printf("Please enter a number: ");
number = scanf("%d", %26amp;number);
cube = test(number);
printf("The cube is %d\n", cube);
return 0;
}
int test(int first)
{
int a, b;
b = first;
a = b * b * b;
return a;
}
I can't figure out what's wrong. Any help would be greatly appreciated!
How do I pass parameters in C?
Here is yours problem:
%26gt;%26gt; number = scanf("%d", %26amp;number);
scanf first scans for the desired formatted string and stores the value in number, but returns the number of extract tokens, 1 in this case, which gets stores also in numbers. After that line, numbers will always be one.
correcct it to:
scanf("%d", %26amp;number);
and it should work also.
Also, you can simply implement test as
int first (int n) {
return n * n * n;
}
Reply:in your program,error part is number=scanf("%d",%26amp;number);
if you use this statement, the output is 1.
Reply:when you compile what does it do, does it give you a correct number or does it output wrong, im not good with C but i do know C++ and that program is pretty much the same as my C++ i know, my yim is in my profile, if you want to yim me i can help you through it
btw, i wouldnt call the main function as void just leave it blank ()
#include %26lt;stdio.h%26gt;
int test(int first);

{

Outlook COM Add-In with C#?
I was asked to create an Outlook COM Add-In using C#.NET. Anybody have any advice or sample code (using event handlers to manipulate the ItemSend event). It's supposed to fire every time an email is sent asking the user if they want to save the email. If they say yes, it presents their Outlook folder structure for them to pick from; if they say no, it moves the email to the Deleted Items. I'm so lost as a beginner C# programmer. I've never done add-ins, com objects, or event handling. Please help!!!!

What is the standard format for beginning C++ code (pre-code text)?
I've found multiple suggestions, and am curious about the "best" or most widely used. I'm a novice C++ programmer, and am wondering what the most common basic beginning of a C++ source is.
What is the standard format for beginning C++ code (pre-code text)?
For most of the applications that you will be writing in an introduction course, your source will be laid out as follows:
// helloworld.cpp
// 27 June 2007
// Print "Hello World!" to the console.
// Include necessary headers
#include %26lt;iostream%26gt;
// Use the standard name space
using namespace std;
// Main entry point
int main() {
cout %26lt;%26lt; "Hello World!\n";
return 0;
}
Reply:/*The following is pretty standard: Dont forget to comment */
# include %26lt;time.h%26gt; //Header files
main ()
{
application code goes here
}
Reply:#include %26lt;headerfile(s)%26gt;
#define %26lt;global constant(s)%26gt;
%26lt;global function(s)%26gt;
int main()
{
%26lt;main program%26gt;
}
Reply:You need to clarify what you mean. Are you referring to the comments often seen at the beginning of a source file? Or do you mean actual code? Sorry, but I can't do mind reading, so you will have to add in additional details or repost your question, spelling out exactly what you mean.
I suggest you take a look at popular C and C++ libraries. SGI's STLPort, some of the more well-known libraries on Sourceforge, and so on, are good starting points. Exploring the Linux kernel code will allow you to see how they structure their source files as well.
And for the record, there is no standard format.

How can one suppress/change order static routine call in C++/C ?
This is for C/c++ programmer. I'd like to know how can we suppress/change order of static routine which are executing from code automatically at startup. You don't need to bother about whats routine are for here, just imagin they are called whenever ur application started.
How can one suppress/change order static routine call in C++/C ?
When you have an OO language, my suggestion will always be to use those OO features.
That said, for C++ I would model objects and use their constructors to get a good start in which I can determine the order of construction by calling as needed. Please see the fist link below on how to manage static construction.
So don't think about "functions" but "state/objects" and their "initialization".

How did you learn c++ ?
please only answer this if you are a c++ programmer.
how long did it take you?
are you using it now?
How did you learn c++ ?
yes... I am using C++ now... I am making a games engine at the moment with it.
It took me about 2 weeks to fully understand C++. I didnt just learn the 'Console Application' side, I also learned the proper Win32 and MFC stuff also.
Note:: There are not 'many' places at University that cover win32, so learning that will give you a better understanding to C++!!
If you are new to programming, you may do better to start off with something like Visual Basic (VB). Learn how to use the objects and place code in them.
If you are familiar with some programming, have you tried Java?
Once you understand languages like VB and know how to utilise it effeciently, then give a shot with C++.
When you do learn C++, learn the basic (the console application) and practice using the input and output streams like 'cin' and 'cout'... or the C style of 'printf' and 'scanf, etc'. Learn the extras that VB doesnt do like pointers for example.
Note:: There are MANY decent books on C++ that covers the console application.
For learning the Win32 stuff... I suggest you be very patient towards it, and finding a good book on win32 may be hard to find (I havent found ANY).
I suggest thorough examination into the internet for Win32 tutorials.
I hope this makes things easier for you...
All the best!!!
Reply:Well, it has taken me about 2 1/2 months to get to where I am now, that is, about high intermediate. The best way to learn, other than books and courses, is to .. program. You learn to fix your mistakes and you get a real sense of satisfaction when you complete it! Get some books out the libary or enroll in a course and just learn it, be patient with yourself. Then, when you have an okay grasp of the basics, come up with a list of programs you would like to make and make them.
No, I am not using it now, but I used it about 10 minutes ago to finish building a 2d game I have been working on.

What is the best way to learn C++?
I'm a well-versed C programmer and have recently started reading the C++ programming langauge (3rd edition) by Stroustrup (creator of C++), but was wondering if any one had any suggestions for me.
What is the best way to learn C++?
You are absolutely already on the right track. TCPL by Stroustrup is the best book out the for learning C++. I came from a similar background. I programmed in C for many years before moving up to C++. The transition from procedure oriented coding to object oriented coding can be a little difficult, but the more you immerse yourself in it, the easier it will get and the more power that you realize from it. There have been times where I've written code in C++ and been almost in disbelief by how quickly and effectively I was able to do it, whereas in C, it would've taken 10 times as long and would have 10 times the bugs.
You're on the right track. Just keep on truckin'.
Reply:Maybe try looking into a college class or tech school just teaching that class you need. Good Luck
Reply:That's an excellent book which covers pretty much everything C++ has to offer. Try to do all the exercises after each chapter and take into consideration the suggestion Stroustrup is pointing out... It can help you a lot.
Another thing is don't focus on just one book and practice as much as you can.
Reply:I would say that book is your best bet. You already know how to program, and learning C++ isn't that huge of a jump from C at least with your preexisting knowledge.

Using Windows.h in C++?
hi, I'm a new c++ programmer who's trying to learn more about windows programming. I'm currently working with Visual C++ 5.0 Express and I've downloaded then installed the Platform SDK package. Unfortunately, I'm still having trouble including the windows.h package. I've been told that all I need to do is include the correct libraries..I just have no idea how to do that yet %26gt;%26lt;. Any help would be greatly appreciated. Thanks in advance.
Using Windows.h in C++?
The compiler doesn't know where to find windows.h. You can either put the whole path in front of the file name, or you can teach VC++ where to look. Eventually you'll need to link to the lib files too, so may as well configure VC++ to know where everything is...
I don't have 5.0 Express, so I can't tell you exactly what menus to look for. In my version of VC++, it's under Tools\Options. Tab over to directories, and add the include and lib directories for your SDK, and also the directories for your VC++ installation.
Here's an example, but you'll need to find the appropriate paths on your machine (hint. Just search for Windows.h, then copy the path)
Include files:
C:\Program Files\Microsoft SDK\Include
C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE
(plus I have lots more)
Lib files:
C:\Program Files\Microsoft SDK\Lib
C:\Program Files\Microsoft Visual Studio\VC98\LIB
(etc.)
Reply:#include %26lt;windows%26gt;
I don't use VC++ so I'm not sure what you're seeing...but in Borland and Metrowerks it really is as simple as the above.
Reply:use #include %26lt;windows.h%26gt;
windows is in include folder path .. not in the project..

Reply:C: A Reference Manual (5th Edition) by Samuel P. Harbison and Guy L. Steele is pretty much on the same order as K%26amp;R's white book with the big blue C, but it goes into a lot more detail. Neither of these books is fun to read; they're references, rather than tutorials, but eventually, you need to know all the rules in order to program well.
P J Plauger wrote a book on the Standard C Library. It not only familiarizes you with the functions you need not reinvent, but it shows you the code. You can learn a LOT about writing code by reading code. Reading good code (like P J's) will teach you some things. Reading bad code (as long as you know it's bad code) will teach you far more.
The Waite Group's "C Primer Plus" by Stephen Prata and Mitchell Waite is an excellent tutorial. The current editions list only Prata, not Waite as author, but I assume it continues the tradition. The book contains enough humor to make the learning process easier.
Programming on Purpose: Essays on Software Design by P. J. Plauger isn't about C so much as it is about general programming, but it's something every good programmer needs to learn. There's actually a series here. The first book is far more important than the other two combined.
The Elements of Programming Style by Brian W. Kernighan and P. J. Plauger is another book every good programmer needs to read. This one is more C-centric than the Programming on Purpose books.
Reply:K %26amp; R is the best book on C. Read that book from cover to cover and do all the questions you will know C well after that.

How do I make a Messagebox show in Visaul C++ 2005?
I'm a Visual Basic/C# programmer and am now trying to transition over to C++a bit. I can really use help tho, see I want to learn how to make a simple message box show in C++. How can I transfer somthing like msgbox("yo") to C++?
Also maybe even changing to another form (vbcode: form2.show)
Any help appreciated
Thanks
How do I make a Messagebox show in Visaul C++ 2005?
if its CLR u are making;
use this
MessageBox::Show("Hello!");
Reply:MessageBox(
hWnd,// handle of owner window
"Apple Computers Suck!",
"Alert!",
MB_OK
) ;
Reply:MessageBox(NULL,"yo","Message Form Caption",MB_OK);

What to learn after learning fundamentals of C++?
I've decided to learn C++ as a hobby, and maybe a job will come out of it down the road. I'm trying to build myself a little road map of what to learn. After you learn the fundamentals of C++, what do you learn next? I've checked out some Windows Programming books, but most seem to be geared towards the C programmer?
I'd like to learn how to build small applications, and games. Can someone please suggest some books?
What to learn after learning fundamentals of C++?
First learn Datastructures. Classes are very important to proper C++ development, so learn it, and use it. There's something satisfying about being able to declare and object you've made and give it near English instructions.
I'd learn OpenGL and/or DirectX for game programming, there's alot of higher level math in them (many texts bog you down with proofs, which you may or may not want/need).
Then if you're going toward web, there's
HTML, JAVASCRIPT, PHP, SQL, JAVA, ASP, JSP
probably in that order.
Reply:select and learn your tools in c++...
learn opengl in c++ or directx in c++...
learn to develop using third party frameworks and integrating with other languages and formats..
you can work with c++...good show...now use it to branch out..
if you wanna get into hardcore gaming and stuff...study the long lost art of assembly programming..
windows and mac api's are geared towards c instead of c++ for backwards compatibility and standards...but you should have no problem working with them in c++...
Reply:After the basics, you would need to shift into Windows Programing. This is a lot more complex, but well be the meat of what you well use.

Emulate microphone input (C#)?
I would like to know if there is any way to emulate microphone input. for example if im on skype or something and i want to show a song to the person im talking to. instead of putting the microphone up to the speaker, is there any way to emulate the microphone input so that it sounds perfect?
also, i am interested in how such software would work.i am a C# and C++ programmer and would like to know how i would go about making a program that does this.
thanks for your help

C++ - what's the default method of opening a file passed to main via *argv[]?
I'm a self-taught C++ programmer, and I stumbled across the second method of main(), being main(int argc, char *argv[]) of course.
The first thing I did was create a small sample program that simply displayed the value of argc and all the values of argv[] that were passed to it. After experimenting with it a bit, I noticed that argv[0] is always the command line text used to execute my program, and the other argv values contain everything else that was passed to it. My question is, where can I go to learn more about the standard methods of passing programs arguments?
I was interested about learning the following in particular:
-How are parameters starting with tags such as -o, -f, -a, and so on usually handled?
-I noticed that, if a file opens the program via a file extension associan, argv[1] contains the location of the file calling my program. How am I to know when argv[1] is a file location, and not a usual parameter? Should I check for C:\? I've just been checking for "*:\"
C++ - what's the default method of opening a file passed to main via *argv[]?
The truth of the matter is that C++ doesn't do any handling of files/flags/parameters whatsoever. When you pass extra command lines to a program, the strings themselves are passed as char arrays (char []) sequentially into the elements of argv[] (an array of char arrays). When a space occurs in the command line, that serves as a delimiter, so every time a space show up, a new char array is added to argv[] and argc is incremented. The one exception to this delimiter rule is when you use quotes on the command line. A quoted string is passed in its entirety as a single argv element. Thus, if you ran MyProgram.exe -o -f -a C:\Program Files\MyProgram\Program Data\test.dat then argv will be an array of size argc containing the following char arrays:
argv[0] = MyProgram.exe
argv[1] = -o
argv[2] = -f
argv[3] = -a
argv[4] = C:\Program
argv[5] = Files\MyProgram\Program
argv[6] = Data\test.dat
making argc=7. Thus if you wanted to retrieve the original command line, you could do something like the following:
string argument="";
for(int i=0; i%26lt;argc; i++)
{
argument+=argv[i];
if(i!=argc-1) //add spaces to all but the last element
argument+=" ";
}
which will result in argument containing exactly what was placed on the command line. Notice how the path argument was split into multiple char arrays because of the spaces in the path. This is sometimes a big problem if not handled correctly. You will have to decide how your program will need to parse argv[] depending on expected input and how you plan on handling it. Notice also that argc contains one more than the number of command line arguments (because argv[0] is the program name itself, useful sometimes when you want to title a window or change your output like in a help printout of how to use the program depending on the name of the exe itself, meaning if the user renames the file it will still show the proper command line to use!). You have to be careful to check argc before you try parsing the command line though or you'll get out of bounds errors, leading to your program crashing or using invalid data at best, taking down other programs or even the OS at worst, though you'll need an older OS to make those happen really). Once you have properly parsed your command line and have gotten the string "C:\\Program Files\\MyProgram\\Program Data\\test.dat" finally, you can use your favorite method for opening files from path, ranging from C's FILE pointer to more complex methods in C++, MFC, Win32, ATL, or your own self-written file class. Have fun!

try opening the file in append mode . that is sa follows
FILE *fp;
fp = fopen("abc.txt","a");
// now write in the file whatever you wanted ,
// it will be appended ( a simple way)
//for writin a character
int putc(int ch , FILE *fp);
// now the charactrr pointed by "ch" will be appended
// or you can get the character from console as
do
{
ch=getchar();
putc(ch,fp);
}while(ch!= "$");
.........................

Microsoft Visual C++ vs Borland Turbo C++ ????
I use Borland Delphi and now i want to move to C++, but i'm confuse which tools i should use, Borland Turbo C++ (which i'm familiar with their vcl) or Microsoft Visual C++ .
which one is most used by visual c++ programmer ?
any suggestion ?
Microsoft Visual C++ vs Borland Turbo C++ ????
That question is like asking what is the best browser Internet Explorer or FireFox, or like asking what the best search engine is Yahoo, Google, MSN, etc. It is all a matter of preference, or what you are used to using.
Some people use Borland, some people use Microsoft. I, myself use Microsoft Visual C++. The reason is because I started off using Borland, but everybody at the company was using Microsoft, so I switched. I went to an interview recently and they were using both tools, the company had merged 2 different groups into 1. So, you might want to check out which industry is using which tool, then go from there. I don't know that much about Borland to comment about their program, but Microsoft has a domineering effect in the industry, IMO.
Reply:If you want to work professionally, it's Microsoft.
If you work for fun or just to quickly learn something, use whatever you prefer.

Can a programmer make around million $ a year? if yes what kind? (C, C++)?
Hello Garfield, that's an interesting question. I did dream in the past of becoming a millionaire computer programmer but I have now come to realize that it takes more than just skills in programming (C++, C, or any other kind of programming language) to get the cash flowing. You must first begin by understanding the computer software market. For example, if you're into developing software for mobile-based platforms (mobile phones, PDAs etc), then you may want to do some research on the current market trends concerning these specific products. To sum it up, you're not going to get much from just focusing on computer languages, because there are just too many of them out there. Reaping a million dollars from programming certainly isn't impossible, but you've got to have an entrepreneur's mindset to complement your skills in programming. It's not about the language, it's about the market which you wish to tap into. For more information, you may wish to visit http://www.entrepreneur.com for some idea. Good luck and all the best in your quest to become a millionaire programmer! ;-)

C++ really confused?? msdn, sdl, api ext......?
I am a beginner c++ programmer. Only have been working in console mode but would like to move onto win32 or win64 apllications and eventually games. When i search on the net for C++ tutorials i get terms like sdl, msdn. api and i have know idea what they mean. Also i downloaded a sdl library for dev-c++ and linked it. is the sdl library a standerd or are there other versions. does it work with opengl or directx. If possible i don't want to program using the .net framework. It's a ok for nissness applications but not games because you need mor control over the GUI. I don't know where to start when it comes to win32 programming? any help would be appreciated?
C++ really confused?? msdn, sdl, api ext......?
Well, its good that you want to enter the complex world of graphics programing. Welcome to real business :)
To start you first need to brush your skills with drawing simple graphics and moving them around the screen. You can start with simple things first, say pure C in a DOS based environment and create simple graphics, move them around and create complex shapes with simple objects like rectangles and polygons.
When you get a good grip on that you can start using the win32 model. For that you can get some books first, on Windows graphics API. MSDN (Microsoft Developers Network) is a good resource for getting most information about Microsoft platforms. No need to get into .NET if you feel you dont need it.
The topic of graphics programing is rather complex to be discussed here but there are plenty of books in the market to get you going...
Happy Programing.
PS, do send me a copy of your first game :)
Reply:If you are a newbie then you should first learn assembly, which is relatively simple, and then move on to C++ which is more complicated.
Reply:Win32, OpenGL, SDL, DirectX are APIs. You use an API with
a programming language to create graphics. To create GUI apps, I use Java or VB.net, I don't bother with win32 but that's just me personally. There is a good win32 tutorial here.

its showing 100 100 100 99 99
but i thought 99 99 98 98 99
Solve this...any c++ programmers out there..?
This is due to the fact that the compiler execute printf from right to left internally but prits the output Left to Right. So if you look at the printf this way you will understand the output. i.e
1st execution will be ++ptr
2nd execution will be ptr++ and so on......
Reply:The print( ) statement with all the incremented and decremented ptr arguments can give different results on different C compilers, because there is no rule for the compiler about the order in which the arguments should be evaluated.
b, c, d and e are not declared, so the program should not compile anyway, and they are not initialised, so if it somehow compiles, the results of their print( ) statements could be anything.

Visual C++ Programmers... Please help...?
Is it possible to change workgroup settings to member of domain settings for My Computer using the Visual C++ language?
If it can, do you know any sites I can refer to or do you know any syntaxes that is responsible for changing workgroup to domain?

You do this sort of thing using the WMI interface, this kind of enterprise level scripting is usually done using VBScript.
Use:
std::system("cscript.exe someVBScript.vbs");

To all c++ programmers, PLEASE HELP!.?
I've asked this question before, but didnt really get clear answers.
i am embarking on a journey to learn C++.. and i was wondering if i can use C++ to create something like IRCX pro. and also a web chat control. Any ideas on where to start the code, or what i should start working on first?
To all c++ programmers, PLEASE HELP!.?
i know c++ very well, but never heard of IRCX pro....???
Reply:IRCX pro. Tell more about it.
Reply:Well, you will have to learn the Standard C++ language first.
You will have to learn how to use the compilers and so forth to develop with C++
Then you will need to know about the operating system you want to work on. For instance, if it is windows, you would have to learn the WinAPI or similar like OLE, MFC, etc. The operating system should control issues like a graphical user interface (GUI). A GUI is the thing you are using right now, if you use a mouse to interact with it, and it is graphical and not just a command line.
You also need to know about algorithms, so you can design or choose the best one for your program.
You may not need a GUI for the web chat control, but this is the basic procedure you are going to have to go through.
If you know all of this, the way to start would be.
Design the program you want, describe what you need and what the program to do. Review this description, and go into further detail with another description. Repeat until you can think of nothing else.
The things you may need are basic services like, get a file, save text, write text, etc. Have little routines to cover these things. All these things should be dealt with in the description above, with the little things being the finest detail you could get.
Build on top of these services by adding them together to create a bigger module. Repeat until you have made the program similar to how you designed it. If you change anything, go back to the description, as you may need to change more than you think.
Reply:to create a chat program, you should use C++ Compilers in windows like Visual C++.
and you should learn how to use Sockets
but i offer you Borland Delphi
it is very easier and also powerful for programming in Windows
and Delphi 7 has a chat program as a Demo internally that you can learn how to write a chat program
Reply:you will get clear answer if you will ask clear question...
do you really think this information is enough?? i m C++ guy...but i dont know what is this IRCX pro. and you can create web chat application..but not sure about control..are you using Visual C++??

Is it dangerous to mix the C with the C++ language.?
I'm a beginner C++ programmer, i'v noticed that there are a lot of C tutorials that allow the programmer to use the win32 API without any extra support. What i was thinking, is it possible to use objects and classes and incorprest that into a C but use a C++ complier.
Is it dangerous to mix the C with the C++ language.?
Yes, you can mix the two. C++ is a superset of C *but* there are some subtle differences that can cause a headache now and again.
One big item no one here has mentioned is that because C++ supports function overloading it "mangles" function names. If you are using a unit compiled by a C compiler you must declare the header file with extern "C" scope. In essence this tells the C++ compiler not to mangle the functions names in the C++ manner but to use the C naming convention. Doing this will allow your program to link properly.
Example:
extern "C"
{
#include "some_C_header.h"
}
Reply:You can combine ANSI standard C and C++ since C++ is simply 'enhanced C'. The result is C++ code
Reply:Yes C++ is an extension of C so ANYTHING you see that is done in C WILL work in C++ ... its not dangerous whatsoever to mix the two simply because they are one and the same (assuming you use C++, since it is a superset of C)... You mention win32 APIs and i've used those within C and in C++ without any problems at all. In fact you can even not bother with objects and classes all together (making it simply a C program, for the most part) and still compile it fine as C++. C++ gives you extensions that you have at hand, it's just a matter of whether you want to use them that differentiates C and C++.
Reply:You can download a free version of Microsoft Visual C++ at the URL below. It will recognize the difference between C and C++, based on the extensions of the file names. It has built-in facilities for handling the windows API.
Yes, you can mix C and C++, but remember that most callable routines in C++ are inside of an object. So you will need to tell your C code how to get "inside" the objects, probably by treating them as "structs". Usually it is not necessary to use C if you are using C++, since C++ can do everything that C can.
Reply:Absolutely not, C++ is a superset of C, which means everything contained within in C you can do. There are a few differences. For example, in C++, main must return an int. Also, structures are declared slightly different, but you can still use the C way. Win32 API is written in C, so it should be no surprise that it works. MFC is the Win32 API wrapped in C++ classes. The important thing to realize though, when using C header in C++. Normally you include %26lt;string.h%26gt;. C++ headers leave off the extension. So many people will think %26lt;string%26gt; equates to %26lt;string.h%26gt;. This is not true. All C libraries should begin witth a 'c'. So %26lt;string.h%26gt; equates to %26lt;cstring%26gt; and %26lt;stdlib.h%26gt; to %26lt;cstdlib%26gt;, etc.

C programmers help me please?
want help in a C program
in which i have to display tables of numbers upto the no which user enter
but imust use all of these following
1)pointer
2)function
3)recurtion
C programmers help me please?
ok a function is just a way to divide up the code to do something for you. A pointer points to an address in memory where something is stored, and recursion is a process in which an algorithm is repeated.
Ex:
int NumberArray[100]; //makes an array to store up to 100 integers
int HowLarge; //variable for how many numbers are to be in the array
int *GetNumbers() {
cout%26lt;%26lt;"How many numbers are you going to input?"%26lt;%26lt;endl;
cout%26lt;%26lt;"Choice: ";cin%26gt;%26gt;HowLarge;
for(int i=0 ; i%26lt;HowLarge ; i++) { //the recursion part, it gets user input to add any numbers in the array
cout%26lt;%26lt;"Input Number "%26lt;%26lt;i+1;cin%26gt;%26gt;NumbersArray[i];
}
}
//ok pretty easy, gets numbers and puts them in an array.
void ShowArray(int *Array) { //now we will show the array
for(int i=0 ; i%26lt;sizeof(Array)/4 ; i++) { //cycles through the array
cout%26lt;%26lt;"Number "%26lt;%26lt;i+1%26lt;%26lt;" of the Array is: "%26lt;%26lt;Array[i]%26lt;%26lt;endl;
}
}
that should do it. If you have any questions about the code look at the refrence below.

C PROGRAMMERS!! Write a program to do the following.....?
Write a program to do the following:
(a) use a loop to print out the numbers from 1 to 50; the end result should look like this:
1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30
31 32 33 34 35 36 37 38 39 40
41 42 43 44 45 46 47 48 49 50
(b) in main() you will have a loop that generates the line number for each line. It will pass
this line number to a function; the function will use the line number to determine the
column values to print out. note that the coordinates of any particular value are (row,
column) with (1, 1) in the upper left corner. NOTE: I rewrote this bullet point to make
the requirements more clear.
(c) do this without using arrays, any kind of lookup table, or just hard-coding values, i.e.,
don’t do this
if (row == 1)
printf(" 1 2 3 4 5 6 7 8 9 10");

{
print(row);
}
}
Reply:use string formatting (printf), it accepts a format code, and some datas, then output the data in the way described by the format code.
for your particular need, you'll need to iterate on this ten times with for:
for (n = smallest; n %26lt; smallest + 10; n++)
printf("%2s ", n)
after that, print a newline
Note: The code above need to import stdio.h
EDIT:
The code above is simple, first the heart of the code is the string formatting:
printf(formatcode, data1[, data2, ...])
This line would print a string with a format defined in the format code. The format code ("%2s ") is a string, as you can see. This particular format code reads as follow: the data is inserted ("%") with width of 2 ("2") as a string ("s") and there is a space in the end (" ").
(string formatting is quite complex to be explained, so for further information about string formatting, see: http://www.cs.utah.edu/dept/old/texinfo/... )
Then, we iterate over the string formatting function ten times per function call using a for-loop. As we know, C (and most other programming language) doesn't automatically print a newline after a print function, so the next call to printf would print the next number beside the last number. At the end of the loop, we print a newline so the next call to the function would print everything on the next line.

Reply:use string formatting (printf), it accepts a format code, and some datas, then output the data in the way described by the format code.
for your particular need, you'll need to iterate on this ten times with for:
for (n = smallest; n %26lt; smallest + 10; n++)
printf("%2s ", n)
after that, print a newline
Note: The code above need to import stdio.h
EDIT:
The code above is simple, first the heart of the code is the string formatting:
printf(formatcode, data1[, data2, ...])
This line would print a string with a format defined in the format code. The format code ("%2s ") is a string, as you can see. This particular format code reads as follow: the data is inserted ("%") with width of 2 ("2") as a string ("s") and there is a space in the end (" ").
(string formatting is quite complex to be explained, so for further information about string formatting, see: http://www.cs.utah.edu/dept/old/texinfo/... )
Then, we iterate over the string formatting function ten times per function call using a for-loop. As we know, C (and most other programming language) doesn't automatically print a newline after a print function, so the next call to printf would print the next number beside the last number. At the end of the loop, we print a newline so the next call to the function would print everything on the next line.

C++ programmers please answer this question?
I am writeing a very drifficult mathmatical program and I extremlly
need to make a tree of opraters.
I've made a structure like this:
struct tree_struct{
struct tree_struct *left;
char node;
struct tree_struct *right;
};
I need to make an array of this new type,and use it as a stack.so
I did so:
struct tree_struct *stack[4];
and by using 'new'(or malloc in c) I got memory for this pointer.
my problem is in this assignment :
tree-%26gt;left= stack[1];
why this assignment is not true ?I don't know?!!
please help me.
thanks for spending your time to answer my question.
C++ programmers please answer this question?
You have an allocation problem...
is you stack[1] previously allocated like: stack[1]=new struct tree_struct;?
if so than tree-%26gt;left=stack[1] should be valid (but be carefull to previous allocate the "tree" var...).if tree is NULL the tree-%26gt;left is ilegal...
Reply:I have a few questions to ask before i can answer ur question:
1) How exactly are u allocating the nodes of the tree.. plz show me the intended statement
2) Is the array storing the mem of the new nodes?
3) if u intend to do tree_struct-%26gt;left=stack[1] u atleast need to use a handle to access the member... i really dont understand what u're doing there. Perhaps a completed code segment would help.
Reply:wat is your exact problem ???
i cant get you ...
the stack starts with 0 or 1 ????????????

Which is a better compiler----Dev C++ or Microsoft Visual Express 2008?
Why?

Dev C++ isn't a compiler. It is an IDE. It uses MINGW, which is based off of GCC.
So are we talking compiler or IDE? With that said, Microsoft latest compilers 2005 and 2008 are excellent, and they are ANSI compliant, so that argument about being proprietary is bs. Sure you can down that path, but you are not required. The only quirk I have found between the two was in a student's program, where when compiled in Dev-C++ it caused the OS to throw an exception, and it didn't in Microsoft. My conclusion was based on the code, that Microsoft compiler initialized the variable with 0, and thus prevented the exception; whereas, GCC didn't. You can look at this as either good or bad.
Now as far as IDEs, Visual C++ is slower to load, but beyond that it is far superior to Dev-C++, especially when it comes to debugging. The debugger in Dev-C++ is still problematic. The intellisense in Dev-C++ is also much slower than that with Visual C++.
I personally usually have more than one compiler, and have both of these installed, plus some others, but if you were only going to go with one I would go with Microsoft's. I also find Visual Studio's error messages to be more verbose and precise.
Classes are only part of C++, and not C. They are used to support object-oriented programming. Object-oriented programming is programming in which data and the particular functions that perform work on that data are combined into structures called classes that act as a blueprint to make objects.
Classes are very similiar to structures. In object-oriented programming, you make objects. For example, you can make a class called Car. This car has variables to hold the make, model, and year of the car in the class. It also has methods or functions to perform operations on that class or change the data or state of that class. From this class Car, objects can be created. For the most part a class is a complex data type, just like int, bool, char. An object is an instance of the data type. It is like a variable name that is declared.(eg. int x)
Reply:I use Visual Studio because friend and foe agree that it's by far the best IDE out there. Admittedly, MS does not completely adhere to all standards (it's spelled 'proprietary' btw) but if you as a programmer are knowledgeable you can always force yourself to abide to standards.
And if you want a light footed compiler that adheres to standards, you should go for gcc... :-)
Reply:i use Dev C++ i tend to avoid Microsoft's propriatery stuff...
Microsoft usually adds their own set of garbage into the mix. Dev C++ has a much lighter footprint and is fully-functional.
Reply:I use Dev always have done and always will,

2) It is not microsoft
I have it on my 2 desktops and my laptop, it is light and works on most OS even the old 95-Me for windows

If C doesn't work out for you, try to learn BASIC. Yes, BASIC is old, but it's easy to learn.

C++ Programmers, need help. would you?
I wrote this program and i compiled it successfully, this program runs successfully, but when it retrieves data from user the program get closed. whats the prob?
Here is my program and my compiler is Dev-C++
# include %26lt;iostream%26gt;
using namespace std;
int main ()
{
float grade;
printf ("Please enter your grade : ");
scanf("%d",grade);
if (grade %26gt;10){
printf("You have passed the test...");
}
else
{
printf("You havent passed the test...");
}
cin.get();
cin.ignore();
return 0;
}
C++ Programmers, need help. would you?
There are two problems:
1. In the scanf the %d means the input is an integer, but you declared the variable as a float.
2. Also in the scanf, you need to pass a reference to the variable, not the variable itself.
So change it to scanf("%f",%26amp;grade);
And it will work for you. %f means float, and %26amp;variable means take the address of (pass by reference.)
Alternatively, you can declare grade as an int, and keep the %d.
--------------------------------------...
Yes, you're going to have a problem with bogus inputs.
You could check the return value of the scanf call.
if !(scanf("%f", %26amp;grade) {
printf("Rerun the program and try putting in a number this time");
return 1;
}
Reply:I am guessing the enter keystroke you pressed to send your number input to the program zipped you past the cin.get statement and returned (ended). If that´s not the case, you can always through in some trace statements and a few getchar()´s at the end (or step through with a debugger).
Reply:In DEV-C++ you need to add, before your return 0; this linke
"system("PAUSE");"
Reply:cin.get will read a white space because it doesn't expect to read anything from the input. If you run your program from cmd line it won't close automatically after running it (because the cmd session is still active).
The easy way would be to request the user to type in a key to continue, something like...
printf("Press any key to continue...");
scanf("%c",%26amp;key)..
This will require to store useless data in your program and of course it can be avoided. The alternative would be to "pause" the system until the user decides to end the session manually. Just type
system("PAUSE");
at the end and it will pause the program until the user press a key to exit.

{

Reply:I think it's because the scanf doesn't take the "return" key after the grade : it is still in the buffer, so cin.get() catches it at once, and your program closes without waiting.
In C, you can address the problem in a nasty way by putting a "fflush(stdin);" just after your scanf. There are prettier ways of doing it, but I just can't remember them right now.
I guess if you know the representation of the return key in your system (\n, \r\n, \r), you can make scanf catch it for you at the end of its first parameter (but your code may have portability issues).

C PROGRAMMERS!! homework help please...?
Write a function that, given a 2D array, will determine the minimum and maximum
values of the array. Use the following two arrays:
40 35 30 25 20
20 30 40 50 60
45 55 65 75 85
30 35 40 45 50
200 300 400 500 600
1000 245 78 123 85
981 1001 575 99 333
(a) Use pointer notation for accessing any array elements; don’t use subscript nota-
tion. For example, within your function use *(*(a + i) + j) instead of a[i][j].
(b) Your function should be able to handle 2D arrays with any number of rows and 5
columns. Don’t hard-code array dimensions other than what is required to create
the arrays, i.e., don’t use something like this:
int rows = 4;
int cols = 5;
(c) Print the maximum and minimum values from main()
This Program must work in Microsoft Visual Studio.
Thanks!
