I won't comment on that usage of AI because I could complain about it for hours. You're courageous to learn programming while being surrounded by people who show their great vibe-coded achievements (while not learning anything at all). Don't give up, it's very fun even after 20 years of writing any kind of application.
C and Java are a bit difficult as first languages because you have to learn a lot of concepts at the same time. Anyway, if you have any question, don't hesitate to spam !learn_programming@programming.dev and I'm sure people will be happy to help.
Test réussi, bravo !
