If your design desires virtual dispatch into a derived course from the base class constructor or destructor for features like file and g, you may need other approaches, like a submit-constructor – a different member purpose the caller will have to invoke to finish initialization, which might safely get in touch with file and g since in member features virtual calls behave Commonly.
