How do i make a C program that will convert Binaries to Decimals? Im a really bad programmer i admit. T_T?

How do i make a C program that would:


1.) Convert Binaries to Decimal


2.) Hexadecimal to Decimal





Really Hard for me to do, I am a really bad programmer, but i can understand the codes. Please help me, it would really help me if you give me the algorithm or the logic or codes to makes these possible.

Here's some pseudo code for you.





Binary to decimal:





Set result D to 0


While binary digits are available {


Get next binary digit into B


D = D * 2 + B


}


D is the decimal result





Hex to decimal:





Set result D to 0


While hex digits are available {


Get next hex digit into H


D = D * 16 + H


}


D is the decimal result
Reply:here is a C pseudocode.





binary-to-decimal(int b)


{


for(i=b,j=0;i%26gt;=0;i/=10,++j) {


d = d+(i%10)*(2 raised to the power of j)


}


return d;


}





hexadecimal-to-decimal(char *h)


{


for(i=last letter of h,j=0; i is at the first letter or more; move i by one letter toward the first letter,++j) {


d = d+(int)i * (16 raised to the power of j);


}


return d;


}





homework? you gotta learn programming and C by yourself for your own sake.
