Objective
This practical tests your skills in writing classes. It also requires a planned application of logic
and code structure.
Problem
In this practical assignment, you are going to implement a simple Rock, Paper, Scissors game in
C++. Two players compete and, independently, choose one of Rock, Paper, or Scissors. They
then simultaneously declare their choices. The winner of the game is determined by comparing
the choices of the players. Rock beats Scissors, Scissors beats Paper, Paper beats Rock.
Your design and implementation needs to adhere to the following interfaces.
Player (abstract class)
char makeMove( );
string getName( );
Referee
Referee( ); // constructor
Player * refGame(Player * player1, Player * player2)
// returns the reference to the winning player
Your submission should contain
Implementation Details
Computer Player
For this assignment, to make things simple, we assume that the computer player only plays Rock
and has the name "Computer"
Human Player
A human player object gets its move from user input. The test system will expect an interface
where the prompt: Enter move: is displayed and the move is input on the keyboard (ie each time
the human player makes a move it will prompt the user to enter a move and expect the user to
type a character among R, P, and S followed by pressing the return/enter key.
The human constructor should take a single string which is the human's name. If this string is not
passed as a parameter, the name should be set to "Human".
Gradescope marking is strict on this, ensure your prompt matches this exactly and does not print
any other prompts.
Referee
The referee class will match two players and return a reference to the winning player. In the case
of a tie, the referee will return a nullptr.
The main
The main program will create the referee and players, and then ask the referee to adjudicate a
game. The main function may create any number of players/referees and call play as many times
as it wants.
Main will then print the name of the winner.
For example, if the human player named Mei plays P the output should be Mei Wins. Another
example: if the human plays R, the output should be It's a Tie. If Mei plays S, the output should
be Computer Wins. (recall the dump computer player always plays rock).
The main purpose of this practical is for you to practice organizing and writing classes and to
recognise how your implementation of your classes can change without having to change the
code in main.
In testing, your code will be tested against our own testing main which will only compile against
the approved interfaces..
