Hw4 grading information

10 Points total.

3 points if the hw4.txt and .cpp files are copied into your
  handin directory (even if you don't get them compiled and run).

8 points if you have at least one of the files compiled and run, and 
  you have the correct answer in hw4.txt.



Note: If you have correct answers in your hw4.txt file but do not 
      have the compiled programs (s, f, and i) in your directory, 
      we will assume you have cheated by copying off of a friend.
      This will get you a 0 for the assignment and worse...
      So don't do that.
