Static member

Static members are called static members by adding the keyword static before member variables and member functions.

Static members are divided into:

1. Static member variables all objects share the same data in the compilation phase allocation memory in-class declaration, out-of-class initialization

Example:

# includeusing namespace std;class Person {public: static int m; / / all objects share the same data}; int Person::m = 0 governance / in-class declaration, out-of-class initialization 2. Static member functions all objects share a function static member functions can only access the static member variable # includeusing namespace std;class Person {public: static void func () {cout
