The Static keyword is used to describe the member attributes and member methods in the class. The final keyword can only be used to define the class and method. The final keyword cannot be used to define the member attributes, because final is a

We will define member functions in the class, and we also want to define member function pointers. Therefore, we need to solve three problems: first, how to define the class function pointer, second assignment, and third use.I define a
