Question

It's writing a simple rock paper scissors game strictly following the instructions.

INSTRUCTIONS:
If the user selects 'p':

1. First the program should call a function named getComputerChoice to get the computer's choice in the game. The getComputerChoice function should generate a random number between 1 and 3. If the random number is 1 the computer has chosen Rock, if the random number is 2 the user has chosen Paper, and if the random number is 3 the computer has chosen Scissors. (Hint: return an int from this function and make the function have no arguments). This function is REQUIRED to be a value returning function (do NOT make a void function).



2. Next the program should call a function named getPlayerChoice to get the user's (player's) choice in the game. Have the user's choice be represented by a number just like the computer's was. The getPlayerChoice function should display a menu similar to the one below and then get a 1, 2, or 3 as the user's choice for Rock, Paper or Scissors. Do not allow the user to enter an invalid choice - they must enter 1, 2, or 3 (use integers for the menu on this instead of chars). (Hint: return an int from this function and make the function have no arguments). This function is REQUIRED to be a value returning function (do NOT make a void function).
Rock, Paper or Scissors?

1) Rock

2) Paper

3) Scissors

Please enter your choice:



3. Next the program should display what the user chose and what the computer chose. You will need to convert both the user's and the computer's integer choices of 1, 2, or 3 to the corresponding strings: Rock, Paper, or Scissors. The display should be similar to the following (in the example below the user chose 3 for Scissors and the computer chose 2 for Paper)
You chose: Scissors

The computer chose: Paper



4. Next the program should call a function named isTie (Hint: have the function return a bool and take two arguments) to see if the game was a tie. This function is REQUIRED to be a value returning function and must take TWO arguments (do NOT make a void function). The game is a tie if both the computer and user made the same choice. If the game was a tie display the appropriate message. An example of a tie is shown below with the appropriate message on the third line.

You choose: Scissors

The computer chose: Scissors

It's a TIE!



5. If the game was NOT a tie, the program should next determine if the player (user) has won the game. You should use a function called isPlayerWinnerto do this, the function should take two arguments (the player choice and the computer choice and return true if the player is a winner and false if the player is not a winner). This function is REQUIRED to be a value returning function (do NOT make a void function) The function is required to take two arguments.

After calling the function, based on the result of it, if the player has won the program should display a message similar to the one below telling the user they won. In the example below the user's winning choice is Rock and the computer's losing choice is Scissors. (Remember the rules for winning and losing are at the top of the page)

You choose: Rock

The computer chose: Scissors

You WIN!



6. If the game was NOT a tie and the user (player) did NOT win this means the computer won and the program should display a message saying the user has lost. In the example below the computer's winning choice is Paper (the user's losing choice is Rock). Do not make this complicated, if it was not a tie and the player did not win the computer won.

You choose: Rock

The computer chose: Paper

Sorry you LOSE.



If the user selects q: Quit the program

If the user selects anything other than p or q: Display an error message.

The program should keep re-displaying the menu and let the user play as many games against the computer as they would like.

------------------------------------------------------

The point of this assignment is to divide the program to two cpp files(called play.cpp and playTest.cpp) and one header file(called play.h).

Also, play.cpp should include

#include "play.h" #include <ctime>

using namespace std; string convert(int choice) // moved to a implementation file { string s = ""; switch (choice) { case 1: s = "Rock"; break; case 2: s = "Paper"; break; case 3: s = "Scissors"; break; } return s; }

--------------------------------------------------------------

and testPlay.cpp should include

#include <iostream> #include "play.h" #include <ctime> using namespace std; int main() { char select; int player, computer; //srand(time(NULL)): srand(13);

-----------------------------------------------------------------

and play.h should include

#include <iostream> #include <string> #include <stdlib.h> std::string convert(int); // moved to a header file

---------------------------------------------------------------

It is due by today so it's urgent!!!!!!!!!!!!!!!!!!

bool isPlayerWinner(int,int);

#endif // PLAY_H_INCLUDED

//Getting computer choice

//Getting user input

}while(ip < 1 || ip > 3);

//Returning input

}

//Check for tie
bool isTie(int player, int computer)

//Function that checks whether player is winner or not
