Question

I have a class like::

Class Test
{
  public:
  void Check(){//dosomething};
  static void call(){//I want to call check()};
};

Because call() is a static member, so it can’t call non-static functions, so I think to use Check() in call() is to create Test pointer and then point to Check(), but I think it is not good, is there a better way to do this?
I can rewrite all of things in the static function, so I don’t need to call Check() again, but what I want is to reuse the code in Check() and avoid repeated code.

Since you need an instance, you either have to create one, use a static instance, or pas it to call():

Class Test
{
  private:
  static Test instance;

  public:
  void Check(){//dosomething};
  // use one of the following:
  static void call(Test& t){ t.check(); };
  static void call(){ Test t; t.check(); };
  static void call(){ instance.check(); };
};
