To explain the notation of friendship as explained in the textbook. Friendship: The friend function of a class can access the public and non-public members of the class. A friend function cannot access variables directly. It has to use object name and dot (.). Suppose there are two objects of two different classes: In the above diagram, we can see that one function can only access their data and the other function can only access their info, but they cannot access each other’s data and info. But what if user needs to access both data and info, so we use Friend function. By using friend function, access will be possible for both the classes. To use friend function, simply add friend in front of member function. For example, voiddisplay() friendvoiddisplay() { // Body { // Body } } Regular function Friend function Negative aspects of friendship: The members of the friend class cannot access the main class members and it does not acknowledge polymorphism.
