How to Optimize this piece of C code...??

int c = no, diff = u - d;
            while (no--)
                for (d = u; d < p[no开发者_StackOverflow社区]; d += diff)

The best optimization, for size, speed, cleverness, clarity, and anything else you may think of, is to have no code.

So, just remove those 4 lines from your source(s) and you've optimized your code.
