Furthermore, how do I access protected base class members?

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:

  1. A pointer to a directly or indirectly derived class.
  2. A reference to a directly or indirectly derived class.
  3. An object of a directly or indirectly derived class.

Also Know, 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.

Similarly, you may ask, can objects of a class access protected members?

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.

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 protected in OOP?

Protected means that a class and its subclasses have access to the variable, but not any other classes, they need to use a getter/setter to do anything with the variable. A private means that only that class has direct access to the variable, everything else needs a method/function to access or change that data.

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

protected - accessible in the class that defines them and in other classes which inherit from that class.

What is a friend function in C++?

C++ Friend Functions. Advertisements. A friend function of a class is defined outside that class' scope but it has the right to access all private and protected members of the class. Even though the prototypes for friend functions appear in the class definition, friends are not member functions.

What is this pointer in C++?

C++ this Pointer. Every object in C++ has access to its own address through an important pointer called this pointer. The this pointer is an implicit parameter to all member functions. Therefore, inside a member function, this may be used to refer to the invoking object.

What are class access modifiers?

Access modifiers (or access specifiers) are keywords in object-oriented languages that set the accessibility of classes, methods, and other members. Access modifiers are a specific part of programming language syntax used to facilitate the encapsulation of components. A class cannot be declared as private.

What is difference between public/private and protected in C++?

Private members are accessible within the same class in which they are declared. Protected members are accessible within the same class and within the derived/sub/child class.
