Write a program that will demonstrate destructor function

Write a program that will demonstrate destructor function. The program that uses the following properties – class names- test; two integer type private member variables- e,f; one constructor function test(); one destructor function ~test(); one public member function add_display(). Constructor function test() assigns the values for e, f; add_display() 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();

    ~test();

    void add_display();

};

test::test()

        {

           cout<<"Constructor Function "<<endl;

            e=10;

            f=20;

        }

test::~test()

{

    cout<<"Destructor Function"<<endl;

}

void test::add_display()

            {

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

            }

 Int  main()

 {

     test  p;

     p.add_display();

     return 0;

}
