    No, Jasen that would only be true of pre-increment which you and Darin
habitually use. I habitually use post-increment largely because I do not
habitually use C++.

    The while (while(*s++){};) loop evaluates *s, and only if not zero
increments s - that's what post-increment means. On the next iterations it
looks at it again until *s=='\0'. Then it terminates.

    It would make a difference only if the part in braces referenced or
altered s or *s. It doesn't.

    If you don't believe me, look at it in debug.

Best Wishes,
Bill.
