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.

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

if (list[index] > max)
