Option 2: Rock, Paper, Scissors Game

Create C++ program that lets the user play the game of Rock, Paper, Scissors against the computer. Be sure to divide the program into functions that perform each major task.

// Function Prototypes

int getUserChoice( );

int getComputerChoice( );

void determineWinner(int, int);

void displayChoice(int);

1)Create function getUserChoice that displays the menu and validate the choice:

Game Menu

---------

1) Rock

2) Paper

3) Scissors

4) Quit

Enter your choice (1-4)://If the user enters 4, the program should end.

2)Create function getComputerChoice. When the program begins, a random number in the range of 1 through 3 is generated.

If the number is 1, then the computer has chosen rock.

If the number is 2, then the computer has chosen paper.

If the number is 3, then the computer has chosen scissors.

(Don't display the computer's choice yet.)

3)The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard.

4)Create function displayChoice to display the user's choice and computer's choice

5)Create function determineWinner to displays a message indicating the winner.

A winner is selected according to the following rules:

If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.)

If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors cuts paper.)

If one player chooses paper and the other player chooses rock, then paper wins. (Paper wraps rock.)

If both players make the same choice, the game must be played again to determine the winner.

Input Validation: Display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu.
