In this program we will learn to create Destructors in c++ programming language.

Destructors Program in C++

// C++ program to demonstrate example of destructors

#include <iostream>
using namespace std;

//Class Declaration
class Demo {
private: //Private Data member section
    int X, Y;

public: //Public Member function section
    //Default or no argument constructor.
    Demo()
    {
        X = 0;
        Y = 0;

        cout << endl
             << "Constructor Called";
    }
    //Destructor called when object is destroyed
    ~Demo()
    {
        cout << endl
             << "Destructor Called" << endl;
    }

    //To take user input from console
    void getValues()
    {
        cout << endl
             << "Enter Value of X : ";
        cin >> X;
        cout << "Enter Value of Y : ";
        cin >> Y;
    }
    //To print output on console
    void putValues()
    {
        cout << endl
             << "Value of X : " << X;
        cout << endl
             << "Value of Y : " << Y << endl;
    }
};

//main function : entry point of program
int main()
{
    Demo d1;

    d1.getValues();

    cout << endl
         << "D1 Value Are : ";
    d1.putValues();

    Demo d2;

    d2.getValues();
    cout << endl
         << "D2 Value Are : ";
    d2.putValues();

    //cout << endl ;

    return 0;
}

Output

Constructor Called
Enter Value of X : 10
Enter Value of Y : 20

D1 Value Are : 
Value of X : 10
Value of Y : 20

Constructor Called
Enter Value of X : 30
Enter Value of Y : 40

D2 Value Are : 
Value of X : 30
Value of Y : 40

Destructor Called

Destructor Called
