Write A Program For Copy Constructor In C++

#include<iostream>

#include<conio.h>

using namespace std;

class Example {

   // Member Variable Declaration

   int a, b;

public:

   //Normal Constructor with Argument

   Example(int x, int y) {

      // Assign Values In Constructor

      a = x;

      b = y;

      cout << "\nIm Constructor";

   }

   //Copy Constructor with Obj Argument

   Example(const Example& obj) {

      // Assign Values In Constructor

      a = obj.a;

      b = obj.b;

      cout << "\nIm Copy Constructor";

   }

   void Display() {

      cout << "\nValues :" << a << "\t" << b;

   }

};

int main() {

   //Normal Constructor Invoked

   Example Object(10, 20);

   //Copy Constructor Invoked - Method 1

   Example Object2(Object);

   //Copy Constructor Invoked - Method 2

   Example Object3 = Object;

   Object.Display();

   Object2.Display();

   Object3.Display();

   // Wait For Output Screen

   getch();

   return 0;

}
