(1) For today's lab: circle overlap problem

     Functions that take more than one parameter...


Emacs tips:  CTRL/X S "save all buffers"
             CTRL/X CTRL/S "save current buffer only"

(2) For today's lab: sentinel controlled while loops...



    a number called a sentinel appears in the condition

    For example, the program might tell the user:

        enter a number of exam scores
	enter -1 to quit
	90
	70
	80
	80
	90
	-1
	There were 5 exam scores
	The average score is:  82
	
	(note: 82 is just our guess)

   The idea is that -1 is not really part of the input.
   It just tells the program when to stop going through the loop


   cin >> input;
   while (input != -1)
   {
      sum += input;
      count ++;
      cin >> input;
   }
