Help with Rock, Paper, Scissors Game

[TayKaye]

Hello All,

I am new to this so I am not sure if this is going to post correctly. I am trying to create a rock, paper, scissors game. My issue with my code is I only want the code to repeat if the computer picks the same choice as the user, however, my code is repeating everytime. If anyone could help me with this I would appreciate it!

Thanks,

Taylor

//This program let a user play rock, paper, scissors with a computer.

    //Seed the random number generator
    srand(seed);

    int computerChoice = rand()%3+1;

    cout << "Type 1 for rock\n";

              else if (computerChoice == 1)
              cout << "Rock smashes scissors, computer wins\n";

   }
   return main();

use a loop that checks user vs computer input for equality before doing test for winner/loser.

int userInput;
int computerSelection;
//get user input
//start with computerSelection equal to userInput
computerSelection = userInput;
//now change selection until they are different
while(computerSelection == userInput)
  //get new computerSelection
//then compare userInput and computerSelection with regard to rock/paper/scissors now that they are different.

I tried to work that into the code but when I do it does not display anything after the user puts in a number.

use a loop that checks user vs computer input for equality before doing test for winner/loser.

int userInput;
int computerSelection;
//get user input
//start with computerSelection equal to userInput
computerSelection = userInput;
//now change selection until they are different
while(computerSelection == userInput)
  //get new computerSelection
//then compare userInput and computerSelection with regard to rock/paper/scissors now that they are different.

Just incase what you have in a do..while() loop.

do{//start the loop here
cout << "Rock, Paper, Scissors Game\n";
cout << "You are playing against the computer\n";
cout << "Type 1 for rock\n";
cout << "Type 2 for paper\n";
cout << "Type 3 for scissors\n";
cin >> userChoice; //User enters choice here
cout <<computerChoice<<endl;



if (userChoice == 1)
{
if (computerChoice == 1)
cout << "We have made the same choice. Rematch!\n\n\n\n";
else if (computerChoice == 2)
cout << "Paper wraps rock, computer wins\n";
else if (computerChoice == 3)
cout << "Rock smashes scissors, you win\n";
}
if (userChoice == 2)
{
if (computerChoice == 2)
cout << "We have made the same choice. Rematch!\n\n\n\n";
else if (computerChoice ==1)
cout << "Paper wraps rock, you win\n";
else if (computerChoice == 3)
cout << "Scissors cut paper, computer wins\n";
}
if (userChoice == 3)
{
if (computerChoice == 3)
cout << "We have made the same choice. Rematch!\n\n\n\n";
else if (computerChoice == 2)
cout << "Scissors cut paper, you win\n";
else if (computerChoice == 1)
cout << "Rock smashes scissors, computer wins\n";

}
    }while(userChoice==computerChoice);//The loop continues until there is a winner

And also change the return value of the main method back to 0.

This worked, thank you so much for your help!!!
