Question

C++ Problem. You are coding a simple game called Pig. Players take turns rolling a die. The die determines how many points they get. You may get points each turn your roll (turn points), you also have points for the entire game (grand points). The first player with 100 grand points is the winner. The rules are as follows:

Each turn, the active player faces a decision (roll or hold): Roll the die. If it’s is a: 1: You lose your turn, no turn total points are added to your grand total. 2-6: The number you rolled is added to your turn total. Hold: Your turn total is added to your grand total. It’s now the next player’s turn.

Requirements. • Display the game score every time the active player changes. • Use whatever techniques you think best for creating reliable code which is easy to read and maintain. Do not optimize for computer performance. Choose data structures which are easy to expand, or preferably, automatically re-size themselves (if needed). • Make your output as clear and easy to understand as possible. item Use structured programming or object oriented programming techniques. • You cannot use any data structures from the standard template library. No vectors or anything like that. • Make a simple AI with a random number. Each decision the com- puter rolls, 1-3 hold, 4-6 roll again. • Style guide elements apply: comments, layout, Program Greeting, Source File Header, and variables etc. etc.

Specification Bundles. These are additional requirements for the assignment. You code the specifications from the various groups to control the maximum potential grade you can get for this assignment. The more work you do, the better grade you can get. Specifications are bundled into groups: "A", "B", and "C". You must meet the specifications of the lowest group before I will count the specifications for the highest group. For example, you must meet the "C" specifications before I will count the "B" specifications. If you miss one element of a spec- ification bundle, that is the grade you will get for the assignment - regardless of how much extra work you do. Note: sometimes you will get comments stacking on top of each other - that’s OK even though you would never do that in the real world.

"C" Specification Bundle. 1. // Specification C1 - Time Seed Get the current time and use it for a random number seed. 2. // Specification C2 - Student Name Allow name to accept first plus last name (ie 2 words). Display it somewhere in the output. 3. // Specification C3 - Numeric Menu Use a numeric menu to collect the human players actions. See figure 1 for an example menu. 4. // Specification C4 - Bulletproof Menu Detect and re-prompt if incorrect data is entered.

"B" Specification Bundle. 1. // Specification B1 - Track each turn Keep track of the points each player scores each turn. 2. //Specification B2 - Randomize Start Randomly determine which player starts the game. 3. // Specification B3 - Alpha Menu Switch to an alphanumeric menu. Only accept the letters between the <>’s. See the next page for an example. List specification C3 like this: // Specification C3 - REPLACED. Put this comment right above specification B3. Note: Specification C4 now applies to this alphanumeric menu. 4. // Specification B4 – Resign Option The human can quit the current game and automatically restart a new one. See figure 2 for an example menu.

"A" Specification Bundle. 1. // Specification A1 - Main Event Loop Run the program in a main event loop. Prompt the player when the game ends if they want to play another game. Use a ’y’ or ’n’ prompt to stop playing games. 2. // Specification A2 - Group Stats Keep track of the number of games played, who won and lost each game and the number of turns each game took. Don’t forget to keep track of games resigned, too. You can use a struc for this is you wish. 3. // Specification A3 - Current Date Include in the program greeting the current date and time this program started. Use a library to automatically get this, do not ask the client to enter it. 4. Specification A4 - Upper and Lower Case You can accept upper and lower case letters for your menu in specification B3.
