I had to work to make your code run.  Here's the deal.  The while loop is
initialized and then it asks for their input.  If their input is nothing,
then it goes through the rest of the code in the while loop, finishes the
while loop and then the value quit is checked again.  at that point the
value quit == true, and so the loop ends.  Does that make sense?

Also, if someone puts in a blank carriage return on the first one and then a
number on the second, the value continues to be false.
