Trouble with RAND_MAX

At this simple code

int main()
{
   srand(time(NULL));

   const int size = rand() % RAND_MAX;
   int numbers[size];

   int i;
   for (i = 0; i < size; i++)
      numbers[i] = rand() % RAND_MAX;

   for (i = 0; i < size; i++)
      printf("numbers[%d]=%d\n", i, numbers[i]);
   }

Doesn't compile because the size of array isn't const value. Why that happens?? And how it can solve??
