140. When a virtual member function is activated, how is the correct version of the function chosen?
Group of answer choices
The class provides some implementation of a pure virtual function.
The class does not provide any implementation of a pure virtual function. Because there is no implementation, any class with a purevirtual function is called an abstract class and no instances of an abstract class may appear in a program. The pure virtual functions are expected to be overridden in the derived classes.
