Question

Use Dev C++ for program and include all of the following. Im lost.

Objectives: To use If-Statements to affect the logical flow of your program To use Switch Statements *lo design a game and hav e fun Instructions: You need to write a program to play "Rock, Paper, Scissors". Start by have the player input his/her choice 'R', 'S', or 'P". Hint, what data type should you use here? Then have the computer generate its choice randomly (0, 1, or 2). Remember to seed your random generator at the top of the main method. Now that you have the numeric choice, you will need to convert (using a Switch statement) it into a letter ('R', 'S', or 'P'.) Then determine the winner of the game. Remember that Rock crushes Scissors, Paper covers Rock, and Scissors cuts Paper.

Make sure the user enters a letter of R, P, or S and the computer generates a number between 0-2 and changes that number to a letter of R, P or S, using a switch. Make sure the user knows why he/she has won or lost – print a message like “Paper covers Rock” or “Scissors cuts Paper”.

Ask the user how many times he/she wants to play and incorporate that into a for loop or allow the user to keep playing until he/she says to stop using a do-while loop.

Add the code to count how many wins, losses and ties that the user has and print the results at the end of the program before stopping the program.

Allow the user to exit a game, not the program, if he wants to – use a code of ‘X’. Also keep a count of exits from a game. Make sure your run has at least one exit.

Also have the program determine if a user did not type in R, P, S or X and print “Bad Code” and allow the user to continue the game. Run at least once with a “Bad Code”.

Heres what I have so far:

#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
using namespace std;

int main()
{
   char user, computer = ' ';
   int ComputerChoice= rand() % 3;

   srand(time(0));

   //Input Statements
   cout << "Enter your choice Rock(R), Paper(P), or Scissors(S): ";
   cin >> user;

   switch(ComputerChoice)
   {case 0:
       computer = 'R' ;
   case 1:
       computer = 'S' ;
   case 2:
       computer = 'P' ;
   }

  
  
   //Output Statements
if(user == computer)
   {cout << "Its a tie!" << endl;}
      
       else if(user == 'R' )
           {if(computer == 'S' )
           cout << "Rock crushes Scissors. User wins!" << endl;
               else
               cout << "Paper covers Rock. Computer wins!" << endl;}
  
       else if(user == 'S' )
           {if(computer == 'R')  
           cout << "Rock crushes Scissors. Computer wins!" << endl;
               else
               cout << "Scissors cuts Paper. User wins!" << endl;}
      
       else if(user == 'P' )
           {if(computer == 'R' )
           cout << "Paper covers Rock. User wins!" << endl;
               else
               cout << "Scissors cuts Paper. Computer wins!" << endl;}
  

   return 0;

Answer 1

Note: Could you plz go this code and let me know if u need any changes in this.Thank You
