I am having problems with my function returning a winner after I coded the rock scissors and paper function play.   I need to complete it ASAP. Thank you.

 

#include <iostream>

#include <string>

using namespace std;

void play (int winner) {

 string p1, p2;

 

  if ((p1 == "paper") || (p2 == "rock")){

  return 1; }

    

  else if ((p1 == "rock") || (p2 == "scissors")){

     return 1; }

  

  else if ((p1 == "scissors") || (p2 == "paper")){

     return 1;

  }

}

int main()

{

 string p1, p2;

 cout << "Play rock, paper, scissorsn";

 string goOn = "yes";

 while (goOn == "yes") {

  cout << "Player 1: ";

  cin >> p1;

  cout << p1 << endl;

  cout << "Player 2: ";

  cin >> p2;

  cout << p2 << endl;

  int winner = play(p1, p2);

  if (winner == 0)

    cout << "Draw!" << endl;

  else if (winner == 1)

    cout << "Player 1 wins!" << endl;

  else if (winner == 2)

    cout << "Player 2 wins!" << endl;

  else

    cout << "ACK! SOMETHING IS WRONG!" << endl;

  cout << "Do you want to continue? (yes or no): ";

  cin >> goOn;

  cout << goOn << endl;

 }

}

 

I get these compile errors if it helps ...

   return 1; }
