C++ Programming - Constructors and Destructors - Discussion

In case of pass by reference the arguments are passed as values in calling function and received in called function as the address variable so any changes changes done inn called function will affect to the calling function.

@All.

Here is my code.

#include<iostream>
using namespace std;
class Point
{
int x;
int y;
public:
//parameterized & parameterless combine constructor
Point(int x=0,int y=0):x(x),y(y){}
//Copy Constructor WITHOUT REFERENCE
Point(Point* p1)
{
this->x=p1->getX();
this->y=p1->getY();
}
int getX()
{
return this->x;
}
int getY()
{
return this->y;
}

void display()
{
cout<<"x="<<this->x<<endl;
cout<<"y="<<this->y<<endl;
}
};

int main()
{
Point p1(11,44),p3;//existing obj
Point p2=p1;
p2.display();
p3.display();
}


OUTPUT:
x=11
y=44
x=0
y=0
