Question

I wrote a card shuffle program and I am trying to see how I can add a sorting function to the program to sort the players hands before printing them. How would I do this?

#include <iostream>
#include <iomanip>
#include <vector>
#include <algorithm>

using namespace std;
void printHand(int []);
void deal(vector<int> &, int[], int[], int[], int[]);
void unwrapDeck(vector<int> &deck)
{
    for(int i=0; i<=51; i++)
        deck.push_back(i);
}
void shuffleDeck(vector<int> &deck) {
    //Status of cards before shuffling
    cout << "Before shuffling: " << endl;
    for (int i = 0; i < 52; i++) {
        cout << i << ": " << deck[i] << endl;
    }

    random_shuffle(deck.begin(), deck.end());
}


int main()
{
    vector<int>deck;
    unwrapDeck(deck);
    shuffleDeck(deck);



    int player1Hand[13], player2Hand[13], player3Hand[13], player4Hand[13];

    deal(deck, player1Hand, player2Hand, player3Hand, player4Hand);

    cout << "Player 1's Hand is: " << endl;
    printHand(player1Hand);

    cout << "Player 2's Hand is: " << endl;
    printHand(player1Hand);

    cout << "Player 3's Hand is: " << endl;
    printHand(player1Hand);

    cout << "Player 4's Hand is: " << endl;
    printHand(player1Hand);

    return 0;
}

void printHand(int hand[])
{

    const string RANKS[] = {"Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10",
                            "Jack", "Queen", "King"};
    const string SUITS[] = {"Spades", "Hearts", "Diamonds", "Clubs"};

    for(int i = 0; i < 13; i++)
    {
        cout<<RANKS[hand[i] % 13]<< "of"<<SUITS[hand[i]/13]<<endl;
    }

        cout << endl;
}


void deal(vector <int> &deck, int player1Hand[], int player2Hand[], int player3Hand[], int player4Hand[])
{
    int deckSize = deck.size();


    for(int i = 0; i < deckSize/4; i++)
    {
        player1Hand[i] = deck[deck.size()-1];
        deck.pop_back();

        player2Hand[i] = deck[deck.size()-1];
        deck.pop_back();

        player3Hand[i] = deck[deck.size()-1];
        deck.pop_back();

        player4Hand[i] = deck[deck.size()-1];
        deck.pop_back();


    }
}
