The Scuba ride sharing business allows people to book and share a ride on a Scuba boat. The business has three boats for hire, numbered 1-3; each boat travels a different route. A route is divided into steps numbered 0 to s - 1, where s is the number of stops. A Scuba client selects the boat, enters their Scuba id, and the numbers of the stops where they get on and get off the boat. A booking looks like this:
Boat: 1
Stops 0-2
Scuba id: 101
Trip: 0 2
Scuba client 101 has now booked a trip on boat 1 from stops 0 to 2. Multiple clients can book a trip on a boat; they share the cost of the trip.
Assume that this is the only booking for the boat. The boat then goes from stop 0 to 2 and shows a simulation of the trip that looks like this:
Scuba1 with Ed
Stop 0
On: Homer101
Stop 2
Off: Homer101
The boat Scuba1 is driven by Ed. Homer gets on at stop 0, and gets off at stop 2.
A client starts with $100 and is charged $10 for each stage (between numbered stops). If two people share a stage, then they pay an equal amount for that stage; the cost is shared between clients. In this case, Homer is the only passenger and travels two stages, so is charged $20 for the trip. The client data base is shown like this:
Homer (Scuba101) has $80.00
Marge (Scuba102) has $100.00
The system has a menu with 7 choices; a choice is a single character input:
The system always read from file on startup, if a file exists. The full specification is shown in Appendix A, and the base code is shown in Appendix B and posted in Assignments/1. IO traces are shown in io.pdf (formatted, with explanation) and in io.txt (straight text) in Assignments/1.
