Number Systems Conversion in C

Can some one please recommend me a link or the code for converting binary to decimal, hexadecimal and octal. Another for converting octal to binary, decimal and hexadecimal. Thank you and please help. I really do need it. Again, thank you and have a nice day!

 

Check out Decimal, Hex, octal and binary number inter conversion

 

If you are on Unix/Linux system check out "man 3 printf"
It's bit heavy going but concentrate on the section showing the formatting chars.
