program to demonstrate the overloading of increment and decrement operator. (C plusplus or C++)

Aim: Write a program to demonstrate the overloading of increment and decrement operator.

Ans:

#include<iostream.h>

#include<conio.h>

class  A

{

int x;

public:

            A()

            {

                        x=40;

            }

            void  operator ++()

            {

            x++;

            }

            void  output()

            {

            cout<<x<<"\n";

            }

            };

void  main()

{

clrscr();

cout<<"Initial value of x=40\n\n";

cout<<"New value of x after using operator overloading is:\n";

A o1,o2;

o1++;

o2++;

o2++;

o1.output();

o2.output();

getch();

}
