Fungus, I don't follow the logic of your post? I don't intend on programming C++ on a PC, all on MCUs?
Maybe it was my post about C: on PCs that misled you into thinking that? Dhenry had said one needed a good understanding of C: structure, and the colon made me thought he was referring to the structure of the C: directory of a PC, hence asking for clarification as I could not see how this was all so relevant.
