Error array bound is not an integer constant before ']' token-CodePudding

What am I doing wrong in this? Error array bound is not an integer constant before ']' token

   using namespace std;

bool cars_present[20];
int count = 0;
void sortArrayIntegers(int IDs[count]);

struct date
{
   int day, month, year;
};

struct car
{
   int ID;
   char owner_name[20], owner_surname[20], make[20], model[20], phone_number[10];
   struct date reg_date, ns_date;
}car_directory[100];

CodePudding user response：

void sortArrayIntegers(int IDs[count]);

Please try changing this line to

void sortArrayIntegers(int IDs[]);

You dont need to provide a value here
