Friend function:

All members of the access specifiers public, private, and protected of a class can be accessed by a friend function.

Friend functions are not the member functions of a class.

The function prototype for the friend function is declared inside the class.

Even though the function is not considered as the member of the class.

The keyword “friend” is used to represent that the function is the friend function.

All non-friend functions of the class can access the public members in the class.

But the friend function of the class can access all the public, private, and protected members in the class...
