Answer 1

#include <iostream>
#include <iomanip>
using namespace std;

int main() {
    int nominals[10] = {1, 2, 5, 10, 20, 50, 100, 500, 1000, 5000};
    int banknotes[10] = {0};
    int amount;

    cout << "Enter an amout to be payed: ";
    cin >> amount;
    if (amount <= 0) {
        cout << "Incorrect input" << endl;
        return 0;
    }

    int i = 9;
    while (amount > 0) {
        if (amount < nominals[i]) {
            i--;
            continue;
        }
        amount -= nominals[i];
        banknotes[i]++;
    }

    cout << endl;
    cout << "nominal | number" << endl;
    for (i=9; i>=0; i--) {
        if (banknotes[i] > 0) {
            cout << "   " << setw(4) << nominals[i] << " | " << banknotes[i] << endl;
        }
    }
}
