This C++ program demonstrates multilevel inheritance without method overriding in classes. The method val() has not been overridden in the multilevel inherited classes. The val() methods have not been declared virtual, so the V-table doesn’t keep track of the latest version of val() method. Rather uses method val() specified in the Base Class when called … Read more
This C++ program illustrates access control in inheritance. The access control can be managed with three keywords – public, private and protected. The public keyword allows access by every class, the private doesn’t allow access by any class and the protected keyword works just like private except for the classes inherited from the base class, … Read more
This C++ program demonstrates the use of protected members in inheritance. The Base Class has all types of members namely – Public, Private and Protected. The public members are accessible from anywhere, the private members are accessible only within class and the protected members are accessible from the base class or its derived class. Here … Read more
This C++ program illustrates multiple inheritance. The concept of multiple inheritance is used when derivation is to be done from two or more classes. The features available in the classes from which derived class is to be constructed are available in the derived class. Here is the source code of the C++ program which illustrates … Read more
This C++ program demonstrates multilevel inheritance with method overriding in classes. The val() methods have been declared virtual, the V-table always keeps track of the latest version of val() method. As the pointer to an object is upcast to a ‘less-derived’ Class, correct version of the method is called when a particular method val() is … Read more
This C++ program illustrates inheritance. Inheritance allows us to define a class in terms of another class. This also provides an opportunity to reuse the code functionality and fast implementation time. The data member and member functions defined in the base class are available in the derived class. Here is the source code of the … Read more
