Try fscanf(input, "%d", &stars) 
			^
			^ TO ASSIGN INTO AN int, scanf() NEEDS THE ADDRESS

As an aside, I generally avoid testing scanf() values against EOF. scanf()
returns the number of successful assignments (1 in this case), so you may
be a lot safer saying:

	while (fscanf(input, "%d", &stars) == 1)
