1. Using the ideas from this chapter, implement a simulation of another racquet game. See the programming exercises from Chapter 9 for some ideas.
2. Write a program to keep track of conference attendees. For each attendee, your program should keep track of name, company, state, and email address. Your program should allow users to do things such as add a new attendee, display info on an attendee, delete an attendee, list the name and email addresses of all attendees, and list the name and email address of all attendees from a given state. The attendee list should be stored in a file and loaded when the program starts.
