Lab 3.04 has sections Problem 1, Problem 2, Problem 3. Students are asked to decide if there is a problem in the code. But we never tell them what the code is supposed to do.

The example itself seems a bit contrived. I can't imagine anyone writing something like that. This is a bad example to have students study. Let's not do that.

For anyone trying to figure out what we are trying to show them:

1. We are creating local variables in the function named the same as the global variables, but they are assigned after reference.
2. We are creating local variables named the same as global variables, but they seem to be assigned the wrong values.
3. We are using the global variables in the function such that your favorite pet is always cat.
