Thread: substrings

Code:

const char *substr(const char *s, const char *match)
{
  do {
    const char *p, *q;
    //if both strings match it'll end up comparing chars after the string's end
    for (p = s, q = match; *p == *q && *q!=0 ; p++, q++)
      ;
    if (*q == '\0')
      return s;
  } while (++*s != '\0');//i think we want to know if the next char is valid, not the actual

  return 0;
}

Did I just try to fix Prelude's code ?!?
