Answer Posted / sujith

I have been seeing lot of answers posted on top of mine.
here is another highly optimized version.

int str_cmp (const char *s1, const char *s2)
{
while (*s1 == *s2++)
if (*s1++ == 0)
return (0);
return (*(unsigned char *)s1 - *(unsigned char *)--s2);
}
before marking it as not an answer, I urge you to try it once!
Trust me, it works.
