What is a difference between private and protected in C++?
Only the member functions or the friend functions are allowed to access the private data members of a class. The class member declared as Protected are inaccessible outside the class but they can be accessed by any subclass(derived class) of that class.
What is the difference between protected and private?
The difference is who can access those functions. Private = only members of the same class can access the function. Protected = Same as private but derived classes can also access.
What is the difference between protected and private access specification in inheritance?
Protected – The members declared as Protected are accessible from outside the class BUT only in a class derived from it. Private – These members are only accessible from within the class. No outside Access is allowed.
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.
What is the Private in the C++?
When preceding a list of class members, the private keyword specifies that those members are accessible only from member functions and friends of the class. This applies to all members declared up to the next access specifier or the end of the class.
What is a protected variable in C++?
A protected member variable or function is very similar to a private member but it provided one additional benefit that they can be accessed in child classes which are called derived classes. You will learn derived classes and inheritance in next chapter.
What is the difference between protected and default in Java?
The protected specifier allows access by all subclasses of the class in question, whatever package they reside in, as well as to other code in the same package. The default specifier allows access by other code in the same package, but not by code that is in subclasses residing in different packages.
What is the difference between private and public access specifier?
Public member can be accessed from non-child class of same package. Private members cannot be accessed from non-child class of same package. Public members can be accessed from child class of outside package.
What is difference between public and private inheritance?
public inheritance makes public members of the base class public in the derived class, and the protected members of the base class remain protected in the derived class. private inheritance makes the public and protected members of the base class private in the derived class.
Does private members get inherited in C++?
The private members of a class can be inherited but cannot be accessed directly by its derived classes. They can be accessed using public or protected methods of the base class. The inheritance mode specifies how the protected and public data members are accessible by the derived classes.
