Question

I need help sorting the item that was sold the most using this function:

void sort ( int listLength, int amount_sold[ ], float price[ ], string item_name[],bool (*compare) (int, int))

{ ……

if ((*compare) (amount_sold [i], amount_sold [j]) ) …. /*since they are parallel arrays, it is important that all arrays are sorted at the same time*/

   for(int j = i +1 ; j < listLength ; j++){
       if(amount_sold[i] < amount_sold[j]){
           //swap amount

           price[i] = price[j];
           price[j] = temp;
           //swap item name
           temp_s = item_name[i];
           item_name[i] = item_name[j];
