    Sorting numbers in descending order

    Hi, I've been working on this program and I don't get the right results for some odd reason. I want "all" of the following numbers to be in descending order.

    12180
    13240
    19800
    22458
    17000
    18125
    15623
    3200
    6500
    11970
    8900
    10000
    6200

    Here's the code, I do get the first three values in the list but none of the other numbers display. I want all the number to display in descending order. Where am I going wrong? Thank you for the help.

    Code:
    void Print_descending(const int list[], int length)
    {
               int index;
               int max;
               
               cout << "The numbers in descending order: ";
    
               max = list[0];
    
               for (index = 0; index < length; index++)
               {
                    while (list[index] > max)
                    max = list[index];
               }
               cout << max << endl;
    }

    The first thing you do is separate sorting from printing

    sort_array( arr, len );
    print_array( arr, len );

    Then do a board search for sorting, it's a popular question.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    try instead of while (list[index] > max)

    if (list[index] > max)
