Optimal Change Calculator TIPS for easier expansion

[KingpinKeys]

So i wrote a program to calculate the optimal change to give for different amounts of change in pence and was wondering how i could implement the checks in the function in a way that i can expand the amount of checks on different coins without having to put more blocks of hard code in.

Any tips welcome :)

 #include <iostream>

using namespace std;
// REMAINDER //
int amountLeft;
// Array For Coins //
int coinArray[6]= {50,20,10,5,2,1};

// GOES THROUGH EACH COIN TO CALCULATE OPTIMAL CHANGE IN PENCE GBP //
void moneySort(int money)
{
    int amountOf = money / 50;
    cout << amountOf << " x50p"<<endl;
    amountLeft = money - (amountOf*50);

    amountOf = amountLeft / 20;
    cout << amountOf << " x20p"<<endl;
    amountLeft = amountLeft - (amountOf*20);

    amountOf = amountLeft / 10;
    cout << amountOf << " x10p"<<endl;
    amountLeft = amountLeft - (amountOf*10);

    amountOf = amountLeft / 5;
    cout << amountOf << " x5p"<<endl;
    amountLeft = amountLeft - (amountOf*5);

    amountOf = amountLeft / 2;
    cout << amountOf << " x2p"<<endl;
    amountLeft = amountLeft - (amountOf*2);

    amountOf = amountLeft / 1;
    cout << amountOf << " x1p"<<endl;
    amountLeft = amountLeft - (amountOf*1);
}

int main()
{
    //VARIABLES//
    int change = 0;

    cout << "Enter your change in pence: " << endl;
    cin >> change;
    moneySort (change);
    cout << amountLeft;
    return 0;
}

#include <iostream>
#include <vector>

constexpr auto coinArray {50, 20, 10, 5, 2, 1};//coins

std::vector<unsigned int> moneySort(unsigned int money);

int main()
{
    for (auto& elem : moneySort(86))
    {
        std::cout << elem << " "; // add a column header to identify coins
    }
}
std::vector<unsigned int> moneySort(unsigned int money)
{
    std::vector<unsigned int> change;
    unsigned int temp{};
    for (auto& elem : coinArray)
    {
        temp = money / elem;
        change.push_back(temp);
        money %= elem;
    }
    return change;
}
