Haha. Thanks for checking. Given the C pre-processor, I'm sure there's a way to maliciously bork it if someone sets their mind to it.

Well I just tried #define int void in C and C++ before a "hello world" program. C++ catches it because main() has to be an int, but C doesn't care. I think it is because C just treats main() as an int by default; older books on C don't even include the "int" part of "int main()" because it's not strictly necessary.

#define int void replaces all ints with type void, which is typically used to write functions with no return value.
