Thread: operator Overloading

I am facing Problem while overloading the += Operator
I've posted My Code here http://phpfi.com/245888 So that you can read it easily. The problems are Commented Out there with

Code:

//Here is the Overloading Problem

Here I am re describing it.
This is the Prototype

Code:

		Point operator +=(int);//Overloading += Operator

This is the operator Function

Code:

Point Point::operator+=(int inc){
	this->x += inc;
	this->y += inc;
	return *this;
}

And this is how I am using this

Code:

pt2+=5;//here is the problem

The Problem is the Output

Code:

Describing Class :              pt1             x = 15  y = 10
Describing Class : pt2 before Copying           x = 4   y = 8
Describing Class : pt2 after Copying            x = 15  y = 10
Describing Class : pt2 after Increment          x = 19  y = 0

It shouldn't Be 19 and 0
Whatever I Do with it Its always 19 and 0 Why ??
How can I solve it ??
I an using g++ on Linux
