    Unhappy static function

    What is the role of a static member function ?

    In case I don't know about static stuff, will declaring and using an ordinary member function offer the same result ?

    class CLASS
    {
    public :

    static void func();
    };

    and

    class CLASS
    {
    public :

    void func();
    };

    Would you mind show me significant differences between the use of both in terms of
    1. linking,
    2. storing,
    3. compiling
    4. functioning


    Thank you

    Re: static function

    To put it short, the major advantage of a static member function is that you don't need an instance of your class (i.e. a concrete object) to call it on. However, this also brings along the major disadavantage: As you don't have an associated object you can't (directly) access any non-static class members from a static member function.

    A static method is basically a function which is closely associated with the class (possibly even private to it), but which does not directly manipulate an object of the class type.
