Q2 program for Assignment operator/unary operator(prefix and postfix )/binary operator overloading .

#include<iostream>
using namespace std;

class A

{
int x,y;
public :
A()
{
x=10;
y=20;
}
void show();
A operator +(A obj)
{
A temp;

temp.x=x+obj.x;
temp.y=y+obj.y;

return temp;

}

A operator -(A obj)
{
A temp;

temp.x=x-obj.x;
temp.y=y-obj.y;

return temp;
}

//prefix expression overloaded

A operator ++()
{
x++;
++y;

return *this;

}

//postfix expression overloaded
A operator ++(int )
{
x++;
++y;

return *this;

}

A operator =(A obj)
{

this->x=obj.x;
this->y=obj.y;

return *this;

}

};

void A::show(){

cout<<x<<endl<<y<<endl;

}

int main()
{
A obj1,obj2,obj3;

obj1=obj1+obj2;//overloaded assignment operator and binary operator will be called .

obj1.show();
++obj1; //overloaded unary "prefix"  operator will be  called .
obj1++; //overloaded unary "post"  operator will be  called .
obj1.show();

obj3=obj1 ;//overloaded assignment operator will be called .
obj3.show();

return 0;
