I’m trying to make a study app for this class I’m in (It’s not a computer class). I want to use c# but I haven’t used it in years, so I am a bit fuzzy on a lot of it. My question is what subjects of c# should I refresh myself on to do so? I want to have a bank of questions that will appear randomly, but also only once, that way I can’t just memorize the order. I feel like it should just be made of if statements and arrays. If I’m wrong just let me know. I do not want anyone to write this for me, just asking what I should freshen up on.
