CPP

#include<iostream>
using namespace std;

class Point {
public:
    Point() { cout << \"Normal Constructor called\\n\"; }
    Point(const Point &t) { cout << \"Copy constructor called\\n\"; }
};

int main()
{
   Point *t1, *t2;
   t1 = new Point();
   t2 = new Point(*t1);
   Point t3 = *t1;
   Point t4;
   t4 = t3;
   return 0;
}

Question 22
