@kaia Now we hit an appendix, which I will not call a conclusion because it's really more of a suggestions-from-me-personally list.
I _used_ to recommend 'learn python the hard way' (even though I don't much care for python), but it has since gone behind a paywall; now, I recommend Beej's guide to C, which is still free and open-source (and frequently updated), starting from the second chapter - https://beej.us/guide/bgc/html/#hello-world
