Public class members and functions can be used from outside of a class by any function or other classes. You can access public data members or function directly by using dot operator. So in above program, the derived class cannot access the member x which is private in the base class, however, derive class has access to the protected and public members of the base class.
So the. Hence the function showdata in derived class can access the public and protected member of the base class. If protected access specifier is used while deriving class then the public and protected data members of the base class becomes the protected member of the derived class and private member of the base class are inaccessible.
In this case, the members of the base class can be used only within the derived class as protected members except for the private members.
