You'd likely find this site a useful reference. It's one we often recommend when starting out:

Whatever course you are in is not giving you much of a foundation in coding based on some of the questions you've asked. That's not all that unusual around here. I'd say that it reflects poorly on the state of teaching of programming languages, but it's not safe to say that. After all, if your teacher was doing a great job, would you even be here? Therefore, those people who come here may be coming from less quality courses. On the other hand, it really comes down to whether you want to learn programming, or not, and that's not something you likely know when you are starting out. Many of us, like myself, never took a course in computers of any sort, so we only learned at whatever pace and in whatever way we wanted to. When you are in a class, you go at the pace of the class....and in the direction the class takes you, which may not be great.

As I said before, debugging is a skill I think should be covered second (right after data types), yet it is often completely ignored, as it was for your class. On the other hand, we get questions ranging from "nobody knows the answer" to super easy. It's often hard to know how to answer because we don't know what lever the person is coming from, especially when it is a question from class work. Is it a good class? Did it cover X? Always hard to say.
