If a constructor has been defined to initialise objects by copying values of existing objects of the same class, it is known as copy constructor.

//Example program
#include<iostream>
using namespace std;

class Point
{
private:
int x, y;
public:
Point(int x1, int y1) { x = x1; y = y1; }

// Copy constructor
Point(const Point &p2) {x = p2.x; y = p2.y; }

int getX() { return x; }
int getY() { return y; }
};

int main()
{
Point p1(10, 15); // Normal constructor is called here
Point p2 = p1; // Copy constructor is called here

// Let us access values assigned by constructors
cout << “p1.x = ” << p1.getX() << “, p1.y = ” << p1.getY();
cout << “\np2.x = ” << p2.getX() << “, p2.y = ” << p2.getY();

return 0;
}
