The Copy Constructor

#include <iostream>
using namespace std;
class Point {
private:
// fields are accessible only to methods belonging to point
double x;
double y;
public:
// constructor accepting two arguments, called by a
// statement such as: Point p(1, 2);
Point(double a_x, double a_y) : x(a_x), y(a_y) {}
// copy constructor
Point(const Point& p) {
x = p.x;
y = p.y;
}
};
int main() {
Point p1(1, 2); // new object using a constructor
Point p2(p1); // new object using the copy constructor
return 0;
}
