Overloading Operator Using A Friend Function In C++

The operator overloading function must precede with friend keyword, and declare a function class scope. Keeping in mind, friend operator function takes two parameters in a binary operator, varies one parameter in a unary operator.

Program:

#inlcude<iostream.h>

#include<conio.h>

class bca

{

public:

int i,j;

bca()

{

this->i=0;

this->j=0;

}

bca(int n,int m)

{

this->i=n;

this->j=m;

}

friend bca operator+(bca&,bca&);

};

bca operator+(bca & d1, bca& d2)

{

bca d3;

d3.i=d1.i+d2.i;

d3.j=d1.j+d3.j;

return d3;

}

void main()

{

bca d1(8,9);

bca d2(10,2);

bca d3;

d3=d1+d2;

cout<<”/n total number of i and j<<”d3.i<<”  “<<d3.j;

getch();

}

Output:

Total number of I and j 18’11
