Question

C++

Write a program that plays the rock, paper, scissors game. Rock beats scissors; scissors beats paper; paper beats rock.

You must use these specific functions in your program. These are the prototypes:

char generateP2toss();

int checkThrow(char, char);

void printStatistics(int, int, int, int);

void finalStatistics(int, int, int, int);

void welcome();

Notes on these functions:

• generateP2toss() will generate the computer's toss (the computer is player2). It returns either an "r", "p", or "s/"
• checkThrow(char char) will check the throw by passing the player1 and player2 throws. It returns an integer: 0 for a tie, 1 for player1 winning, and 2 for player2/computer winning.
• printStatistics(int, int, int, int) prints the statistics for each throw. Parameters are the number of times player1 has won, player2 wins, ties, and the number of rounds.
• finalStatistics(int, int, int, int) is the same as printStatistics().
• welcome() generates you welcome message and instructions.

Note that each game is a rapid-fire round until the user enters "q" to quit. Then those game statistics are displayed.

Allow your user to repeat the entire program if desired. Don't forget input validation loops.

Format your output like this (or improve on it):

***ROCK, PAPER, SCISSORS GAME***



Directions: enter one of these to throw down:

r: rock

p: paper

s: scissors

q: quit and display statistics



        > Rock Paper Scissors Throw! r/p/s/q > r

        > Lose.

        > Rounds: 1 | P1 wins: 0 | Computer wins: 1 | Ties: 0

        > Rock Paper Scissors Throw! r/p/s/q > r

        > Tie!

        > Rounds: 2 | P1 wins: 0 | Computer wins: 1 | Ties: 1

        > Rock Paper Scissors Throw! r/p/s/q > t

        > ERROR: only pick from {r, p, s, q} > s

        > Tie!

        > Rounds: 3 | P1 wins: 0 | Computer wins: 1 | Ties: 2

        > Rock Paper Scissors Throw! r/p/s/q > p

        > Tie!

        > Rounds: 4 | P1 wins: 0 | Computer wins: 1 | Ties: 3

        > Rock Paper Scissors Throw! r/p/s/q > p

        > Win!

        > Rounds: 5 | P1 wins: 1 | Computer wins: 1 | Ties: 3

        > Rock Paper Scissors Throw! r/p/s/q > q



*************

Game results:

*************

  Player 1 wins:    1 (20.00%)

  Computer wins:    1 (20.00%)

           Ties:    3 (60.00%)

         Rounds:    5



        > Play another entire game (Y/N)? > y

        > Rock Paper Scissors Throw! r/p/s/q > r

        > Lose.

        > Rounds: 1 | P1 wins: 0 | Computer wins: 1 | Ties: 0

        > Rock Paper Scissors Throw! r/p/s/q > q



*************

Game results:

*************

  Player 1 wins:    0 (0.00%)

  Computer wins:    1 (100.00%)

           Ties:    0 (0.00%)

         Rounds:    1



        > Play another entire game (Y/N)? > n

        > Game ending....
