Can protected members be inherited in C++?

public, protected and private inheritance in C++ protected inheritance makes the public and protected members of the base class protected in the derived class. private inheritance makes the public and protected members of the base class private in the derived class.

Can Protected be inherited?

Protected data members can be accessed by any classes that inherit from your class. Private data members, however, cannot.

What is the protected keyword in C++?

The protected keyword specifies access to class members in the member-list up to the next access specifier ( public or private ) or the end of the class definition. Class members declared as protected can be used only by the following: Member functions of the class that originally declared these members.

How can a protected member be made available for inheritance?

The protected members are inherited by the child classes and can access them as its own members. But we can’t access these members using the reference of the parent class. We can access protected members only by using child class reference.

How are protected members of a base class when inherited privately in C++?

If a class is derived privately from a base class, all protected base class members become private members of the derived class. Class A contains one protected data member, an integer i . Because B derives from A , the members of B have access to the protected member of A .

What is protected keyword?

The protected access modifier cannot be applied to class and interfaces.

When inheritance is protected private members of base class are?

Private Inheritance is one of the ways of implementing the has-a relationship. With private inheritance, public and protected member of the base class become private members of the derived class. That means the methods of the base class do not become the public interface of the derived object.

What is inheritance in C?

Inheritance is a feature of object-oriented programming languages that allows you to define a base class that provides specific functionality (data and behavior) and to define derived classes that either inherit or override that functionality. Prerequisites

What is the importance of inheritance in programming?

Inheritanceis one of the fundamental attributes of object-oriented programming. It allows you to define a child class that reuses (inherits), extends, or modifies the behavior of a parent class. The class whose members are inherited is called the base class.

Can a base class be inherited as a protected class?

Further, a base class can be inherited as protected. Both of these actions are accomplished by using the protected access specifier. The protectedkeyword is included in C++ to provide greater flexibility for the inheritance mechanism.
