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.
Explicit overriding. In native C++, a derived class function having the same name and parameters as a base class virtual function will *always* override it. In C++/CLI you have the option of using the new contextual keyword to specify whether you want to override a base class function or hide it.
