paper rock scissors

I am using this on Windows and I can't get it to run properly, although it compiles without any problem. The idea of the program is simple: it first is supposed to ask player 1 to enter paper, rock or scissors, and then after they input their answer, it will ask player 2 the same thing and is supposed to tell you who wins, but the program keeps closing after player 2 enters their choice! Any suggestions or advice?

Code:

#include <iostream>
#include <string>

using namespace std;

    

int main()
{
    string rock;
    string paper;
    string scissors; // declare rock, paper, and scissors
    string player1;
    string player2; // declare value of player 2
    cout<<"Player One, enter paper, rock, or scissors: "; // output to player one to enter
    // declare value of player 1
    cin>>player1; //input from player 1
    cout<<endl;
    cout<<"Player Two, enter paper, rock or scissors: "; // output to player two to enter

    cin>>player2; // input from player 2
    cout<<endl; 
    
    
      if (player1==rock && player2==rock)
      {
        cout<<"It's a tie!";
      }
    
      else if (player1==rock && player2==paper)
      {
        cout<<"Player Two wins!";
      }
      else if (player1==rock && player2==scissors)
      {
        cout<<"Player One wins!";
      }
      else if (player1==paper && player2==paper)
      {
        cout<<"It's a tie!";
      }
      else if (player1==paper && player2==rock)
      {
        cout<<"Player One wins!";
      }
      else if (player1==paper && player2==scissors)
      {
        cout<<"Player Two wins!";
      }
      else if (player1==scissors && player2==scissors)
      {
        cout<<"It's a tie!";
      }
      else if (player1==scissors && player2==rock)
      {
        cout<<"Player Two wins!";
      }
      else if (player1==scissors && player2==paper)
      {
        cout<<"Player One wins!";
      }
      else 
      {
           cout<<"Please try again..."<<endl;
      }
  
    system("pause");
    return 0;
}

rock paper and scissors are not initialized.

Instead of string variables rock, paper, and scissors, just use "rock", "paper", and "scissors", for example

Code:

if (player1=="rock" && player2=="rock")

Also, if you were willing to take input as integer values 0, 1, and 2, or convert to them, you could shrink this code down a bit - for example, if you let paper == 2, rock == 1, and scissors == 0, then if the inputs are n1 and n2,

n1 beats n2 if (n1 - n2 + 3)%3 == 1
tie if (n1 - n2 + 3)%3 == 0
n2 beats n1 if (n1 - n2 + 3)%3 == 2

What you need at the end of your program is

Code:

cin.ge(t()

because that will allow you to see who wins.

Thank you robatino, that did the trick!
