FAQs on C++ Programming Tutorials - protected Members Video Lecture - Learn to Program with C++: Beginner to Expert - Back-End Programming

1. What are protected members in C++?
Ans. Protected members in C++ are class members (variables, functions) that can be accessed by the derived classes but not by the objects of the class or any non-member functions.
2. How are protected members different from private members in C++?
Ans. Protected members can be accessed by the derived classes, whereas private members can only be accessed by the class itself. Protected members maintain encapsulation within the class hierarchy, allowing derived classes to access and modify them.
3. Can protected members be accessed by objects of the class in C++?
Ans. No, protected members cannot be accessed by objects of the class in C++. They can only be accessed by derived classes or friend functions.
4. What is the purpose of using protected members in C++?
Ans. The purpose of using protected members in C++ is to provide access to derived classes while maintaining encapsulation within the class hierarchy. It allows derived classes to inherit and modify the protected members, while restricting access to objects of the class or non-member functions.
5. Can protected members be accessed by non-member functions in C++?
Ans. No, protected members cannot be accessed by non-member functions in C++. They can only be accessed by derived classes or friend functions. Non-member functions do not have access to the protected members of a class.
