What is a virtual function in C++?
Simply put, the virtual keyword enables a function to be 'virtual' which then gives possibility for that function to be overridden (redefined) in one or more descendant classes. It is a good feature since the specific function to call is determined at run-time. In other words, a virtual function allows derived classes to replace the implementation provided by the base class.
