A friend function is actually a friend declaration inside a class for an outside function. The intent is to allow the outside function to access all data of the class including private and protected data.

A friend function is used for accessing the non-public members of a class. A class can allow non-member functions and other classes to access its own private data, by making them friends. Thus, a friend function is an ordinary function or a member of another class.

A friend function is a function that is not a member of a class but has access to the private and protected members of the class. A friend declaration can be placed anywhere in the class declaration.
Syntax:-
class classname
{
private:
------
------
public:
member function declaration();
friend return type function name(argument list);
};

Code
#include<iostream.h>


#include<conio.h>
