9.5.3.Share static variable among different class instances

#include <iostream>

using namespace std;

class MyClass {

    static int a;

    int b;

  public:

    void set(int i, int j) {

      a=i;

      b=j;

    }

    void show();

};



int MyClass::a;



void MyClass::show(){

  cout << "This is static a: " << a << endl;

  cout << "This is non-static b: " << b << endl;

}



int main(void){

  MyClass x, y;



  x.set(1,1);

  x.show();

  y.set(2,2);

  y.show();

  x.show();

}
