C++ Programming - OOPS Concepts - Discussion

Thank you all for explaining.

Object cannot be defined as friend.

We can define a friend function (i.e a normal function can be a friend of a class or a member function of a class can be a friend function of another class), friend class (i.e member function of a friend class can directly access private and public members of that class, if which it is defined as friend) and also friend operator function (i.e operator function of one class can be defined as friend function in another class). But object is a run time entity.

Thanks for the explanation.

Why not operator funtion?

Instance of class means object works during the execution of program.

What is mean by instance of a class?

Friend function is used to pass arguments in a class. Class can also be friend but an object is cannot be friend as it is an instance of a class.

Explain the friend function?

How is operator can be friend function explain in detail.
