Thread: Assignment: Rock, Paper, Scissors

Hello! I have been trying to fix my program but it does not work because it only outputs TIE May I ask what I am missing or what I need to fix? Thank you

Rock=1 Paper=2 Scissors=3
The program assumes that the user will always input a valid input (1, 2, or 3). (There is no need to check for invalid input.) The program then outputs one of the following messages: “PLAYER 1 WINS!”, “PLAYER 2 WINS!”, or “TIE.”

Code:

#include <stdio.h>

int findWinner (int nP1, int nP2, int nWinner)
{
    int tie; 
    
    if (nP1==1 && nP2==2) {
        nWinner=nP2;
    }
    else if (nP1==1 && nP2==3) {
        nWinner=nP1;
    }
    else if (nP1==2 && nP2==1) {
        nWinner=nP1;
    }
    else if (nP1==2 && nP2==3) {
        nWinner=nP2;
    }
    else if (nP1==3 && nP2==1) {
        nWinner=nP2;
    }
    else if (nP1==3 && nP2==2) {
        nWinner=nP1;
    }
    else if (nP1==1 && nP2==1) {
        nWinner=tie;
    }
    else if (nP1==2 && nP2==2) {
        nWinner=tie;
    }
    else if (nP1==3 && nP2==3) {
        nWinner=tie;
    }
}

int main()
{
     int nP1, nP2;
     int nWinner;
     
     printf ("Player 1: ");
     scanf ("%d",&nP1);


     printf ("Player 2: ");
     scanf ("%d",&nP2);


     int findWinner;
     
     if (nWinner==nP1) {
           printf ("PLAYER 1 WINS!\n"); 
     }
     else if (nWinner==nP2) {
           printf ("PLAYER 2 WINS!\n");
     }
     else {
           printf ("TIE.\n"); 
     }
     return 0;
}

Sample Run should be this:
Player 1: 1
Player 2: 2

PLAYER 2 WINS!Player 1: 3
Player 2: 3

TIE.
