BOOL vs bool ?

[Christian Graus]

BOOL should be avoided if you're using C++. You should use bool. Christian No offense, but I don't really want to encourage the creation of another VB developer. - Larry Antram 22 Oct 2002 Hey, at least Logo had, at it's inception, a mechanical turtle. VB has always lacked even that... - Shog9 04-09-2002 During last 10 years, with invention of VB and similar programming environments, every ill-educated moron became able to develop software. - Alex E. - 12-Sept-2002

I totally agree. The only place I use BOOL anymore is with my windowing code. If it doesn't have anything to do with windowing, I use a bool. Tim Smith I'm going to patent thought. I have yet to see any prior art.

Yes, but having to add all those != 0 to get rid of that warning is a pain in the butt. I tried using bool 100%, but I found it too annoying with windowing code. Tim Smith I'm going to patent thought. I have yet to see any prior art.

You can use !! instead of != ;) bool b = !!SomeFuncReturningBOOL(); No warning, and easier to type than bool b = SomeFuncReturningBOOL() != 0; - Anders Money talks, but all mine ever says is "Goodbye!"

i dont read every answers but bool is one byte or less. struct DemoSize1 { bool a; } sizeof (DemoSize1) is 1 byte; struct DemoSize2 { bool a; bool b; } sizeof (DemoSize2) is 2 byte; struct DemoSize3 { bool a:1; bool b:1; } sizeof (DemoSize3) is 1 byte; in the last case a and b share the same byte.
