Turning numbers into text and sorting for Card Deck

So I've done the majority of this project (unwrapping cards in ascending order, shuffling them, and dealing them). However, I now have to take what I have, which has been approved, and turn the numbers into text descriptions of the cards( Ace, Hearts, ect) and sort them. I basically have to finish out my showHand function. I'm having trouble figuring out where to start with this. I was thinking of using a struct, but don't know if that would be the correct approach. We have not learned classes and public, so I would want to keep with the approach I've already taken. Here is what I have so far:

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

using namespace std;

using cards = unsigned short;

//Global constants
const int NUM_COLS=13;
const int NUM_ROWS=4;


//Create Function prototypes for card loading and shuffling deck of 
cards
void unwrap(vector<int> &);
void shuffle(vector<int> &);
void printCards(vector<int>);

//Function for dealing cards to players
void deal(vector<vector<int>>&, const vector<int>&);
void showHands(const vector<vector<int>>&);


int main() {

//Declare vector for the number of cards
vector <int> deck;



//Call function for showing cards in ascending order, and shuffling 
cards
cout << "The deck before shuffling: " << endl;
unwrap(deck);
printCards(deck);

cout << "The deck after shuffling: " << endl;
shuffle(deck);
printCards(deck);

//Declare 2d vector for dealing the cards to each player
vector<vector<int>> players(NUM_ROWS, vector<int>(NUM_COLS, 0));

cout << " Before cards have been dealt " << endl;
showHands(players);

cout << " After the cards have been dealt "<<endl;
deal(players, deck);
showHands(players);

return 0;
}

//Function definitions that load cards and randomly shuffles them
void unwrap(vector<int> &deck)
{
//Load vector with ints from 0 to 51
for (int i = 0; i <= 51; i++)
{
    deck.push_back(i);
}

}

// Randomize the cards in the deck
void shuffle(vector<int> &deck)
{
random_shuffle(deck.begin(), deck.end());

}
void printCards(vector<int> deck)
{
for(int j=0; j<deck.size(); j++)
{
    cout<< deck[j] << endl;
}
}
// deal one card to each player in order, repeat until the entire deck 
is dealt
void deal(vector<vector<int>>& players, const vector<int>& deck)
{
int card_count = 0;

for (int cols = 0; cols < NUM_COLS; cols++)
{
    for (int rows = 0; rows < NUM_ROWS; rows++)
    {
        players[rows][cols] = deck[card_count];
        card_count++;
    }
}
}
//Show hand after cards have been randomly dealt to each player
void showHands(const vector<vector<int>>& players)
{
for (int rows = 0; rows < NUM_ROWS; rows++)
{
    cout << "Player " << rows + 1 << ": ";
    for (int cols = 0; cols < NUM_COLS; cols++)
    {
        cout << players[rows][cols] << ' ';
    }
    cout << '\n';
}
}
