Using override keyword to a method in the derived class
meaning the method provides a new implementation to the
overridden method (same signature) in the base class. The
base method must be virtual, abstract, or override.
By default a method is not modified by ‘virtual’. So if a
method in derived class wants to override the base
implementation, it needs to be modified by ‘new’ keyword.
This is called shadowing, not overriding. The method in the
derived HIDES the one in the base class.
