Programming Language is C++

Problem description

For this exercise you will create a version of the Rock, Paper, and Scissors game that is played against the computer. The program will use a number of functions as listed below. The computers move will be randomly generated. While this program will be an introduction to using functions, it will also be a review of data validation and loops. In addition to using functions, you will be using enums.

Program Functionality

The game must use enums to represent both the user and computer moves. Constants should be used where appropriate.

Display a clear set of instructions to the user

Input R, P, or S from the user. Validate the input, if incorrect prompt the user to re- enter until correct. Either upper or lower case is ok.

Get a random computer move.

Display clear output describing the outcome of the game including the user's pick, the computer's pick and the winner.

Ask the user if they would like to play again and repeat the entire game again as necessary.

Required Functions

At a minimum the program should have the following functions:

showInstructions

o no parameters

o tells the user how to play the game o no return values

getUserMove

o no parameters

o get a move from the user and validate (R, r, P, p, S, or s) o return appropriate enum (Rock, Paper, Scissors)

getCompMove

o no parameters

o generate a random value 0, 1, or 2 o return appropriate enum (Rock, Paper, Scissors)

getWinner o two parameters (user move and computer move as enums)

o determine winner as described below o output the results o no return values

playAgain o no parameters

o ask the user if they want to play again o valid the result (y/n)

o return true for y, false for n

Thank you.
