Question

Deriving a class in such a way that that the base class members are not available for further inheritance is known as ___________________

(a) Public inheritance

(b) Protected inheritance

(c) Protected or private inheritance

(d) Private inheritance

I got this question in an online quiz.

My doubt stems from Derived Class in portion Classes of Object Oriented Programming

Answer 1

The correct option is (d) Private inheritance

Explanation: The private members of a class can never be derived to another class. When a class derives another class using private inheritance, all the members become private members of the derived class. Hence these member won’t be available for further inheritance.
