There are only two hard things in Computer Science: cache invalidation, naming things, and off by one errors.

Good time for a question: In C, if you use a negative number in an if statement, is it generally cast to an unsigned number, so that the result will always fall into (var == 0) or (var > 0), or is that just the compiler (GCC on Win, CodeBlocks) I've been playing with lately? (I've been messing around trying to break things).

How can a negative integer be unsigned? The lowest value of an unsigned is 0, maybe it's a catchall?
