Assigning values to and extracting them from a vector

[Slaughtter]

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.

#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);
}
