An interface describes the behavior or capabilities of a C++ class without committing to a particular implementation of that class. Below are two examples of setting default values in a constructor and are equivalent in functionality. Once the prototype was working, I wanted to migrate this to C++ (the main goal of this project is to practice C++). One has to initialise it immediately in the constructor because, of course, one cannot set the value later as that would be altering it. So on and so on.
