Assigning values to and extracting them from a vector

I am writing a program to play rock paper scissors, and I am trying to get a vector to store the result of a given round of play, and output it as a declaration as to who won. I can't figure out how to store the values in the vector properly, and how to use the vector as an argument to output the result of play.

Code:

---

#include <iostream>
#include <iomanip>
#include <ctime>
#include <vector>
#include <cstdlib>
#include <string>
using namespace std;

const string name[4] = {" ", "rock", "paper", "scissors"};

const string roundResult[3] = {"computer win", "player win", "tie"};

void getPlayerChoice(int & choice)
{
       
        cout << "Pick 1 (rock), 2 (paper), or 3 (scissors): ";
        cin >> choice;
        if (choice <=3 && choice >=1)
                choice = choice;
        else
                cout << "invalid choice, try again\n" << endl;

       
               
}


int getRoundResult (int computerChoice, int playerChoice)

{
        if (computerChoice == playerChoice)
        {return 3;
        }
        else if ((playerChoice == 1 && computerChoice == 2)
                || (playerChoice == 2 && computerChoice == 3)
                || (playerChoice == 3 && computerChoice == 1))
        {return 2;
        }
        else if  ((playerChoice == 2 && computerChoice == 1)
                || (playerChoice == 3 && computerChoice == 2)
                || (playerChoice == 1 && computerChoice == 3))
        {return 1;
        }
}

void showRoundResult(int computerChoice, int playerChoice, int roundResult)
{
        if (roundResult == 3)
        {cout << "I chose " << name[computerChoice] << " too, so we tied.\n\n";
        }
        else if (roundResult == 1)
        {cout << "I chose " << name[computerChoice] << ", so I win. "
        << name[computerChoice] << " beats " << name[playerChoice] << ".\n\n";
        }
        else if  (roundResult == 2)
        {cout << "I chose " << name[computerChoice] << ", so you win! "
        << name[playerChoice] << " beats " << name[computerChoice] << ".\n\n";
        }

       
}
void showGameResults(vector<int> results, const int size, int games)
{
        cout << "Game Results\n" << endl;
        cout << "------------\n";
        cout << "Round" << setw(3) << "Result\n";
       
        for (games = 0; games < size; games++)
        {

                cout << games + 1 << setw(7) << roundResult->at(games) << endl;
        }
}

int main()
{
        int games, choice(0), computerChoice, playerChoice, roundResult;

        const int size = 10;

        vector<int> results;

        srand(int(time(NULL)));

        cout <<  "CPS 150 Assignment 10 by -----------\n";

        cout << "\nLet's play Rock-Paper-Scissors!" << endl;

        cout << "We will play 10 rounds.\n" << endl;

        for (games = 0; games < size; games++)
        {
                computerChoice = 1 + rand() % 3;

                getPlayerChoice(choice);

                playerChoice = choice;

                roundResult = getRoundResult(playerChoice, computerChoice);

                results.push_back(roundResult);

                showRoundResult(computerChoice, playerChoice, roundResult);

               

}
        showGameResults(results, size, games);
}

:confused:
The only remark I have is that you should pass the vector by const reference to showGameResults, rather than by value. Also, an instance of vector already knows its own size.
