You are right. even though I've been aware of C++'s existence for some years
this is the first time I actually code in it so it takes some while to get used
to the inheritance and virtual (derived) methods concepts, and considering
there's been a lot on my mind lately besides coding I'm not surprised myself
about the mistakes one after another I tend to make in me presumptions.
