A type-specific template friend class is a friend class that has been declared as a template and is specific to a certain data type. A general template friend class, on the other hand, is a friend class that can operate across all data types. The template keyword is used for type-specific friend classes.

If a base class declares a function to be virtual, and a derived class does not use the term virtual when overriding that class, is it still virtual when inherited by a third-generation class?
