Lab 9 Prelab

More structs this week  We were going to move right along to pointers and dynamic arrays, but a lot of people seemed to have trouble last week, so we're going to take things slow and easy this week, and maybe have a bit more time for question and answer, to be sure everybody is up to pace for the midterm next week.

Which isn't to say you can slack off on the lab, it's still quite a task for the time, but there won't be new syntax and concepts to deal with.
