How to generate multiple numbers in c++

I'm trying to count down from 100 to zero and the max I want to subtract is 10; this is the code I've written but it always subtracts by the same amount every time I run it.

int main()
{
   int total = 100;
   srand(time(0));
   int max = 10;
   int randomNumber = rand() % max + 1;
   while (total > 0)
   {
       total= total - randomNumber;
       cout << total << endl;
   }
}
