Rock paper scissors using functions

[evilsithgirl]

hello everybody. I am trying to write a game of rock paper scissors where the user plays against the computer. The computer picks a random number and the user makes his/her own selection. then the selections are compaired and the winner is selected.

I need to write the following in functions:

get user choice
get computer choice

i was able to get the winner in a function already.

the program works as it stands now but i have no idea how to put the user and computer choice in a function. here is my code

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

void  winner(int selection, int compSelection);

int main()
{
    srand((unsigned)time(0));

	int compSel = (rand()%2)+1;
	int userSel;

	cout << "Welcome to ~ Rock Paper Scissors ~!! I assume you know how to play,";
    cout << " so lets begin. You are playing against the computer. Type 0 for";
    cout << " rock, 1 for paper, and 2 for scissors\n";
	cin >> userSel;

	cout << "Computer Selects " << compSel << endl;

	winner(userSel, compSel);

	system("pause");
    return 0;
}

void  winner (int selection, int compSelection)

{     
	
    if (selection == 0) 
    {
              if (compSelection == 0)
              cout << "It's a tie!\n\n\n\n";
              else if (compSelection == 1)
              cout << "Paper beats rock! Sorry, you lose!\n\n\n\n";
              else if (compSelection == 2)
              cout << "Rock beats scissors! You win!\n\n\n\n";
    }
    
    else if (selection == 1)
	{
               if (compSelection == 0)
               cout << "It's a tie!\n\n\n\n";
               else if (compSelection == 1)
               cout << "Paper beats rock! You win!\n\n\n\n";
               else if (compSelection == 2)
               cout << "Scissors beat paper! Sorry, you lose!\n\n\n\n";
   }
   else if (selection == 2)
   {
              if (compSelection == 0)
              cout << "It's a tie!\n\n\n\n";
              else if (compSelection == 1)
              cout << "Scissors beat paper! You win!\n\n\n\n";
              else if (compSelection == 2)
              cout << "Rock beats scissors! Sorry, you lose!\n\n\n\n";
   }
}

any suggestions?

What is the problem?
Write a function!
int userselection()
{
cout...
cin ...
return an int
}
Do the same with the computerselection...
