Program 5:

100 points                                                                                              due 4/12/02

Objectives:

• use arrays
• use a makefile to compile a program

Specification:

You are going to write a program to play Yahtzee. The necessary functions will be divided up into several groups so that you don't have to write the entire program. This will give you a taste of how big programs are developed as well as teaching you how to use a makefile.

Yahtzee is a game for 2 or more players that uses 5 dice. Each player gets 13 turns. In each turn, a player rolls all the dice. The player may choose to re-roll any subset of the dice two times.

The score for a turn is based on the numbers showing after the third roll. The score is applied to one of the 13 configurations which must be achieved (or forfeited) during the game. The configurations can be played in any order.

A total of 63 or more for the first six configurations earns a bonus of 35 points. An extra Yahtzee in a game earns a bonus of 50 points.

Your assignment is to write the main program which runs the game and one of the function modules listed below. I will provide a makefile and the object code for all the modules except the main program. The header file yahtzee.h has prototypes for all the required functions. You may add prototypes for any other functions that you write to this header file. For compatibility with other modules, you should not change the prototype of any of the functions I have listed. You will also need to get copies of the object files for the modules you aren't writing code for from the p5 directory. dice.cppNofaKind.cppstraights.cppplayer.cpp

functions for rolling and re-rolling the dice
functions to test and score the n-of-a-kind hands
functions to test and score large and small strights
a class that allows the computer to be one of the players

Because I haven't specified the input format for this program, your readme needs to be sufficiently detailed that I can figure out what to type in to the program.

Hints:

• You can do this as a solitaire game if you want. Just set up the loop you need to have the user play 13 hands and then calculate the final score.
• The user will decide which configuration to score based on what dice he has.
• The Player class will have to decide how to choose which hand to score. This is likely to be complicated to do intelligently. A dumb player might just do each configuration in order. A slightly smarter one might score the configuration (out of those remaining to be played) that gives him the highest score for a particular set of dice values.
• Look at the powerpoint slides called classes.ppt for some information that I went over in class.
• iIf you get bored with getting the same dice every time you play the game, you can either use the function randomize() from randomize.h (in the handouts directory) at the beginning of the yahtzee program or add the fillowing to it.

  #include srand( time(NULL)); // at the beginning of the main program.

Testing:

make

Submission:

• yahtzee.cpp
• yahtzee.h (this may be just my file if you haven't added anything)
• At least one of the following:
  • dice.cpp
  • NofaKind.cpp
  • straights.cpp
  • Player.cpp
• object files for the modules listed above for which you didn't write a cpp file
• readme (This should contain your name, the purpose of the program, instructions for using the program, any other explanation that a user might find helpful. anything you might want to remember later (possible improvements e.g.) and any extra information that I might need for grading the program.)
