Yesterday, I saw an interesting related exercise.  Write a program that
reads the lines from a file and outputs the middle line.  The kicker is
that you can't use arrays.  (Note that there's a little ambiguity with
respect to the definition of "middle line" when the number of lines in
the file is even or when there is only one line.  Just pick a reasonable
definition and get to work.)

I'll post my solution in a day or two.
