Copy Constructor

Copy Constructor

• To create a copy of an existing object of class.
• By default class provides copy constructor.

Let's understand with example:

CODE:

#include<iostream>

Using namespace std;

Class Points

{

Private:

    Int x, y;

Public:

    Points(int x1, int y1) { x = x1; y = y1; }

    Points(const Point &p2) {x = p2.x; y = p2.y; }

    Int getX()            {  return x; }

    Int getY()            {  return y; }

};

Int main()

{

    Points p1(4, 11);

    Points p2 = p1;

    Points p3 = p2;

    Points p4 = p3;

    Cout << “Use the copy constructor in class code and print the value of an object four times.\n\n\n”;

    Cout << “p1.x = “ << p1.getX() << “, p1.y = “ << p1.getY();

    Cout << “\np2.x = “ << p2.getX() << “, p2.y = “ << p2.getY();

    Cout << “\np3.x = “ << p3.getX() << “, p3.y = “ << p3.getY();

    Cout << “\np4.x = “ << p4.getX() << “, p4.y = “ << p4.getY();

    Return 0;

}
