here's ur answer
A copy constructor is a member function which initializes an object using another object of the same class. A copy constructor has the following general function prototype
Following is a simple example of copy constructor.
#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;
}
Output:
p1.x = 10, p1.y = 15 p2.x = 10, p2.y = 15
