    Terms

    This is the thread I'm going to be asking about terms in C++... My first one:

    Whats a BOOL (or a bool in openGL)?

    > Whats a BOOL

    If you look through your header files, you will find

    #define BOOL int

    which should answer your question.

    > (or a bool in openGL)?

    'bool' is a standard C/C++ type, not an OpenGL type. It is a one-byte-long value, which can take either the value 'true' or 'false'.

    I'm not 100% sure but I do think that bool is only standard in ansi c++ not c. Windows also defines bool's too.

    If you are going to do a thread on C++ then use the C++ programming board.
    Don't mean to be picky but in C++ bool is either TRUE or FALSE ( notice the uppercaps).

    Again, don't mean to be rude or picky.

    I think you mean, in C++ BOOL is either TRUE or FALSE. By contrast, bool, the primitive type, can take on the values specified by the keywords true or false. There is a difference -- BOOL is an int, which takes on the integer values TRUE or FALSE. bool is a primitive, which takes on the values true or false, which are also keywords.

    bool, true, and false are keywords which are only defined under C++, BOOL, TRUE, and FALSE may be used in C.

    right V

    bool, true, false are keywords

    and BOOL, TRUE, FALSE are defined in headers.
