Lab 2

There is nothing to hand in for this lab. Instead, begin work on homework 5.

I especially want you to finish defining the structures for the world by the end of lab. Please ask questions about the structures, if you have any. If you do not get the structures correct, nothing else will work.

Also make sure you understand what all of the questions are asking. If you have even the slightest doubt, write some of your tests before you begin work defining the functions.
