Give an example of friend classes in C++ and an example of when you would use one. In C++, the friend keyword can be applied to either a function or a class. A friend function or friend class has access to the private members of the class in which the declaration occurs. There are programmers who think that this feature violates the principles of object oriented programming because it allows a class to operate on another classâs private members.
Hereâs a catalog of the archetypal friends that over the course of a life youâre likely to encounter again and again. The Best Friend: The gold standard of friendships. A best friend listens but never judges, helps you out of a jam, tells it to you straight, and often forgives a debt. Best friends resemble invisible friends in that both are most common in childhood (and may not really exist). The Old Friend: Ideally, a lifelong bond that stirs fond feelings and cherished memoriesâunless youâre a celebrity or out on parole. In reality, most old friendships are embedded in a complex economy of favors.
