In this article we will learn to implement a CPP program using friend function. A C++ program is provided below for implementing friend function.
Program is as follows:
#include <iostream>
using namespace std;
class A
{
private:
int x;
public:
A(int p)
{
x = p;
}
friend void display(A &);
};
void display(A &obj)
{
cout<<"x = "<<obj.x;
}
int main()
{
A obj(10);
display(obj);
return 0;
}
Output for the above program is as follows:
x = 10
