What an awful professor! When I first tried to learn pointers, I didn't get it. I tried again 6 months later and suddenly it clicked. The same thing happened for another guy I was learning with.

So the professor just gaslit years of students into thinking they were too dumb to get programming, and also left them with the developmental disability of "if you can't figure something out in a few days, you'll never get it".
