Seeing this makes me realise how fucked I am for my own course because I can't code for shit.

bruh do not lose hope because i've been there. Both this semester and last I hit a wall where i was seriously considering chaning majors. Its all built around those basic building blocks. This program is nothing fancy just if, else, printf, etc. Its taken me two years to be to this point too you're only just now starting, you'll get there. ANYONE can code, trust me. Your biggest enemy in programming is overcomplicating things

I'm also interested in coding, but I want to specifically learn about AI and I don't really know where to start with that.

Even something as complex as AI theory is still built upon the basic foundations of programming I.e. if else statements, while and for loops,  stacks, queues, etc.
