Isn't that kinda cheating? 

I suppose you should also ding me for <string.h>.

It's a valid answer, and meaningful of itself. The follow up questions would bring it back to where we started.

If you're not tired of the game yet, write:

// return true if val is an integer power of 2; false otherwise.
bool IsPowerOf2(unsigned val);
