Write a program to illustrate the concept of operator overloading in C++?

#include<iostream.h>

#include<conio.h>

class a

{

public:

int i,j;

public:

a()

{

i=10;

j=10;

}

public:

void show()

{

cout<<"\n After increment i is:"<<i;

cout<<"\n After increment j is:"<<j;

}

public:

void operator++()

{

i++;

j++;

}

};

void main()

{

clrscr();

class a a1;

++a1;

a1.show();

getch();

}

OUTPUT:-

 After increment i is: 11

 After increment j is: 11
