    Hint. 24 / 10 = 2 remainder 4.

    Or you could read as a string and print out the string in reverse - also allows you
    to easily validate the input - use fgets to read a string if you don't know how to
    already. Tonto's solution is the most common answer to this question, so
    whichever suits you.
    No No's:
    fflush (stdin); gets (); void main ();


    Goodies:
    Example of fgets (); The FAQ, C/C++ Reference


    My Gear:
    OS - Windows XP
    IDE - MS Visual C++ 2008 Express Edition


    ASCII stupid question, get a stupid ANSI
