Write a program that will demonstrate parameterized constructor function

Write a program that will demonstrate parameterized constructor function. The program that uses the following properties – class names- test; two integer type private member variables- e,f; one parameterized constructor function test(int m, int n); one public member function add_display(). Constructor function test(int m, int n) get the value from parameterized object xx(6,7) and assigns the values for e, f; add_output() member function do the addition for e, f and displays the result as output.

#include<iostream>

using namespace std;

class test

{

    int e,f;

public:

    test(int m,int n);

    void add_display();

};

test::test(int m,int n)

{

    e=m;

    f=n;

}

void test::add_display()

    {

       cout<<"Addition is : "<<e+f<<endl;

    }

 int main()

 {

     test xx(6,7);

     xx.add_display();

     return 0;

 }
