Question

Quizplus · Accepted Answer

Abstract classes are defined to provide a base or framework for derived classes. They have at least one pure virtual function and are never intended to be instantiated directly. They often serve as a base class for other derived classes to inherit from and implement their own functionality. Therefore, choice D is the correct statement. Choices A, B, and C are incorrect as they are not applicable to abstract classes.
