Using a static function without an instance of a class, in C ++

Question

I have a class with static functions. I need to use functions without instantiating the class.

Is it possible?

Answer 1

Of course:

class A {
   public:
      static void f();
};

...

A::f();    // call function

Answer 2

No problem, that’s their point.

Or you can use the singleton design template: http://en.wikipedia.org/wiki/Singleton_pattern#C.2B.2B
