    To reflect your original loop in a traditional way, you'd do something like:
    Code:
    for( i = nc; i>=0;i--) ...
    --

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.

    very true but as im new to this i dont understand how the condition ( ; i-- ; )
    does it mean if ( i ) is one less than the previous loop?
    No, in terms of the loop condition it means: while (i != 0). Then you consider that there is a post-decrement in effect.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    im still confused how for(i=nc; i--; ) is the same as while(i != o)
    is there a link you know that i could read up on that?
