Comment

//* C++ STL sort() will sort your's unsorted program sort
#include <iostream>
#include <algorithm>
#include <string.h>
using namespace std;

int main()
{
    string s;
    cin >> s; //! Input: Subodh
    sort(s.begin(), s.end());
    cout << s << endl;
    
    
    //! Array sorting usign STL
    // sort an array in ascending order
    char c[] = {0, 30, 40, 88, 99, 22, 77, 56, 120, 66};
    int n = sizeof(c) / sizeof(c[0]);
    sort(c, c + n);
    cout << c;

    //* Ranged based for loop
    for (int i : c)
    {
        cout << i << " ";
    }

    cout << "\n";
    // sort an array in descending order
    reverse(c, c + n);
    for (int i : c)
        cout << i << " ";

    cout << "\n";
    
    // sort an array in descending order
    sort(c, c + n, greater<int>());
    for (int i : c)
        cout << i << " ";

    return 0;
}
