Overriding allows a child class to provide a specific implementation of a method that is already provided its parent class. Method overriding means having two methods with the same name and same signature, one method in the base class and the other method in the derived class. *) If we use Virtual keyword, then we tell to compiler that this method can be overridden by the derived classes.
