    super/interface keywords

    http://msdn.microsoft.com/library/de.../key_f-r_3.asp

    I learned object oriented programming with java, and in java super and interface keywords exist. But I've never come across those kewords in a C++ source. Yet.. I have the doubt. Are those keywords standard or only another of VC++ add-ons ?!?

    Well, that's because C++ doesn't have interfaces--it has multiple inheritance, and calling a base class constructor is not done with super().

    if I ever need that (big hierarchy tree) I think I'll use
    Code:
    #undef interface
    #ifndef _MSC_VER
    #define interface class
    #else
    #pragma keyword("interface", on)
    #endif

    You can have the same effects in C++, but those are not keywords.

    If you want an interface, create an abstract data type (which is a class that has pure virtual functions -- although, it can have implemented functions too).

    For calling the base class constructor, you must do this in the initializer list.
    The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.
