9.8.1.Initialize variables from base class using initialization syntax

#include <iostream>  

using namespace std;  

  

class MyClass {  

  const int numA; // const member 

  const int numB; // const member 

public:  

   

  MyClass(int x, int y) : numA(x), numB(y) { }  

  

  int getNumA() { return numA; }  

  int getNumB() { return numB; }  

};  

  

int main()  

{  

  MyClass ob1(7, 9), ob2(5, 2);  

  

  cout << "Values in ob1 are " << ob1.getNumB() << 

          " and " << ob1.getNumA() << endl;  

  

  cout << "Values in ob2 are " << ob2.getNumB() << 

          " and " << ob2.getNumA() << endl; 

   

  return 0;  

}

Values in ob1 are 9 and 7
Values in ob2 are 2 and 5
