What Is Protected Inheritance?

What is protected inheritance in C++?

Protected Inheritance − When deriving from a protected base class, public and protected members of the base class become protected members of the derived class.

Private Inheritance − When deriving from a private base class, public and protected members of the base class become private members of the derived class..

How do you implement inheritance?

This makes it easier to reuse the code, makes us write the less code and the code becomes much more readable.

What is private inheritance?
