8 Answers. A class can only access protected members of instances of this class or a derived class. It cannot access protected members of instances of a parent class or cousin class. In your case, the Derived class can only access the b protected member of Derived instances, not that of Base instances.

Simply so, can objects access protected members?

Protected members (C++ only) A protected nonstatic base class member can be accessed by members and friends of any classes derived from that base class by using one of the following: An object of a directly or indirectly derived class.

Similarly, what is a protected class member? Protected members are accessible in the class that defines them and in classes that inherit from that class. Edit: Both are also accessible by friends of their class, and in the case of protected members, by friends of their derived classes.

Subsequently, question is, how can a protected member can be accessed?

Protected data member and method are only accessible by the classes of the same package and the subclasses present in any package. You can also say that the protected access modifier is similar to default access modifier with one exception that it has visibility in sub classes. Classes cannot be declared protected.

Are protected members inherited?

Its only difference occurs in fact with inheritance: When a class inherits another one, the members of the derived class can access the protected members inherited from the base class, but not its private members. With protected , all public members of the base class are inherited as protected in the derived class.

Do private members get inherited C++?

A derived class doesn't inherit access to private data members. However, it does inherit a full parent object, which contains any private members which that class declares. It depends on the inheritance type. If you inherit privately, then the derived class does NOT have access to the Base's private members.

What is difference between protected and private access specifiers in inheritance?

How are protected members different from public and private members of a class?
