#include <bits/stdc++.h>

    int Max = *max_element(array, array + x);
  
    for (int i = Max; i >= 0; i--) {
        cout.width(2);
        cout << right << i << " | ";
        for (int j = 0; j < x; j++) {
            if (array[j] >= i)
                cout << " x ";
            else

int main()
{
    int array[10] = { 19, 3, 15, 7, 11, 9,
                    13, 5, 17, 1 };
    int x = sizeof(array) / sizeof(array[0]);
    Barchart(array, x);
