That's just the way C is. If you want to check "truthiness" (as much as you can in C), just do 'if x'.

Something nice in C is that "if (x)" is always equivalent to "if (x != 0)". NULL is a macro for 0, and so is false. Boolean expressions evaluate to 0 if they don't hold. This isn't true in C++, though.
