CS 2010 Lab 9 Instructor Plan

Imagine a GUI for adding people to a guest list, checking whether someone is there, and removing someone from the list.

• Implement add-guest which takes a string and returns (void), but adds the string to the guest list.

• Implement is-guest? which takes a string and returns true if the given string is on the guest list, false if not.

• Implement remove-guest which takes a string and returns (void), and removes the string fromthe guest list.

• Optional: build a GUI with one text field, three buttons (add, check, remove), and one message (for reporting check results).
