Assignment 5: Yahtzee

Objectives

• to use the factory pattern
• to use the strategy pattern
• to use inheritance

Introduction

Yahtzee is a fun dice game currently marketed by Hasbro.

Assignment

Implement the necessary classes to make the code in /c/cs427/hw5/Required play a simplified version of Yahtzee with no Yahtzee bonuses or Yahtzee jokers.

Design your code to be easily reusable. The current implementation of main uses one of two factories to create a game object. For this assignment, those can be objects that implement the same rules. But for the next assignment, the MysteryYahtzeeFactory should create a version of the game using rules that will be given later. Much of your grade for the next assignment will be based on how much code you have to add or modify to implement the new game. You should think about how to implement other similar games (for example, the standard version of Yahtzee with bonuses and jokers, Yatzy, Generala, and Kismet) to get a good idea of what designs will work well for the next assignment.

Other Requirements and Non-requirements

• Your program should execute with no memory leaks, uninitialized reads, invalid reads, or other memory errors reported by valgrind.
• We will run unit tests for some of the methods required by main, and you may assume that those unit tests will not attempt illegal moves and will pass in only valid DiceRoll objects (that is, valid rolls of five six-sided dice).

Graduate Requirement

For graduate credit, compile with the CPSC527 symbol defined, which enables the code in main that abstracts the current position in the game (scoresheet + current turn + location in turn) into a separate object.

Example

A partial transcript of a game follows. Note that at the end of a turn, the abbreviations of unused categories are displayed in the order the corresponding categories appear on the scoresheet.

Submissions

Submit whatever source code (.cpp and .hpp) files you created and a makefile that builds the Yahtzee executable when make is run with no arguments or with target Yahtzee. Your makefile must assume that the code in /c/cs427/hw5/Required has been copied to the current directory; do not hard-code that particular directory in your makefile.
