It is the only number with all bits set to 1. What happens when you flip all 1? They will all become 0! If the number is anything else, it will contain at least one 1 after being flipped. As we all know, any number that is not 0 is true in an if-statement.

Okay that is really impressive. Where did you learn bit operators (if they are called like that, I'm not quite sure) ?
