I agree. Programming should be simpler than it is. But if you use C's _Bool, I think knowing how it works is important. C has a lot of very odd rules which makes it a particularly bad choice for anyone not prepared to learn them. > A type which holds a flag that is set or unset, but with some sort of > difficulty or complexity about it which means you really need to > dig out the manual.

BartC could equally have said "if you negate an int with a value of 1, you're liable to end up with 4294967295" and used the same printf call to justify it. Something about _Bool must have prompted the idea that it would be really weird, when in fact it isn't. -- Ben.
