/*
 * Lab 3: Fortune Teller
 *
 * In this lab, you'll be implementing a fortune teller, which answers yes/no
 * questions with a randomly-selected response from a pre-generated list.
 *
 * This lab is a follow-along lab: the TA will introduce each part, give you a
 * few minutes to figure it out on your own, then go over the solution before
 * moving on to the next part. You still must have a working solution at the end
 * of lab to get credit, but you should be able to get there by following along.
 *
 * This lab is intentionally short, so use the extra time to ask questions of
 * your TA to make sure you really understand arrays and how they work.
