Hi,

I'm new to objective-c and I saw the "new type" BOOL (YES, NO).

I read that this type is almost like a char.

For testing I did :

NSLog(@"Size of BOOL %d", sizeof(BOOL));
NSLog(@"Size of bool %d", sizeof(bool));

Good to see both display 1 (sometimes in C++ bool just an int and sizeof is 4)

So I was just wondering I there were some issues with the bool type or something ?

Can I just use bool (that seems to work) without loosing speed?

Thanks for answers
