Private and Public Inheritance in C++

Let us understand what does private inheritance mean… Consider a simple example to illustrate the single inheritance. The Program given below shows a base class B and a derived class D. The class B contains one private data member, one public data member and three public member functions. The class D contains one private data member and two public member functions. #include<iostream.h> class B { private: int a; //private; not inheritable public: int b; //public; ready for inheritance void get_ab(); int get_a(); void show_a(); }; class D : private B //private derivation { private: int c; public: void mul(); void display(); }; In private derivation, the public members of the base class becomes private members of the derived class. Therefore, the objects of the derived class D cannot have direct access to the public member functions of the base class B. Hence, if we create an object of the derived...
