Project 1

Due May 21, 2002

You must do at least one of the projects

Level 1: Your goal is to write a program that simulates spinning a European roulette wheel. A European roulette wheel is divided into 37 congruent (and supposedly equal) sectors numbered 0 through 36. The numbers 1 through 36 consist of 18 red numbers and 18 black numbers; the 0 sector is green. In addition, no two adjacent sectors have the same color. A roulette wheel always has a sector that is selected and a roulette wheel can be spun to randomly change the sector that is selected.

Design and implement a class called RouletteWheel that models a real European roulette wheel. Your class should provide services for spinning the roulette wheel, getting the sector that is currently selected (by number), getting the color of that sector, and getting a descriptive text string that describes the sector.
You also need to provide a class that tests your RouletteWheel class; call this class RouletteWheelTester. This tester class should spin the roulette wheel until three green zeros have been observed or until the wheel has been spun 10000 times.

Extra Credit: Allow a way for a user of your RouletteWheel class to create a roulette wheel object that simulates a Las Vegas roulette wheel. A Las Vegas roulette wheel is similar to a European roulette wheel except that it has 38 congruent sectors. The additional sector is called double zero (00), it is green, and it is adjacent to the single zero (0) sector.

Level 2: Your goal is to write a program that simulates a slot machine. The slot machine you will be simulating has three slot wheels. Each slot wheel has the same 7 symbols: apple, banana, cherry, lime, orange, peach, and strawberry. A slot wheel always has a symbol that is showing and a slot wheel can be spun to randomly change the symbol that is showing.
The slot machine can be played for $1. When the slot machine is played, all three wheels are spun and the amount of money the machine will payout is determined based on the symbols showing on each wheel. The following payout scheme is used (all payouts include the players original $1 used to play the game):
- 3 peach symbols (jackpot) -- $129 is payed out
- 3 of the same (non-peach) symbols -- $33 is payed out
- 2 peach symbols -- $7 is payed out
- 1 peach symbols -- $1 is payed out
- All other combinations -- no money is payed out
Design and implement a SlotWheel class that has the necessary attributes and operations (services) to model the behavior for a slot wheel as described above.
Design and implement a SlotMachine class that has the necessary attributes and operations (services) to model the behavior for a slot machine as described above. Your SlotMachine class should have a method called play that spins the slot wheels, prints out the symbols (just their names) that show as a result of the spin, and determines the payout to the user. The payout should be returned to the user of your method as an int. An object created from your SlotMachine class is called an aggregate object because it is made up of other objects (i.e. slot wheels).
You also need to create a class called SlotMachineTester that tests your slot machine. To test the slot machine play it a 1000 times and track how much money you put into the machine ($1 a play) and how much money you get out of the machine. After playing 1000 times print out the net amount of money you lost or made. Would you want to play this slot machine in real life?
