#include <iostream.h>
class Point {
public:
Point( int x1=0, int y1=0) {
x=x1; y=y1; d=x*x+y*y;
}
void print(){
cout<<"x="<<x<<" y="<<y<<” dist=”<<d<<endl;
}
private:
int x, y, d;
};
void main()
{ Point p1(5),p2(6,7),*p;
p=&p1;
p->print();
p2.print();
}

Answer 1

x=5 y=0 dist=25
x=6 y=7 dist=85

Answer 2

x=5 y=0 dist=25
x=6 y=7 dist=85

Answer 3

x=5 y=0 d=25
x=6 y=7 d=85
