You can also comment out a large region in emacs. Mark a region (using a mouse drag or
C-@ followed the arrow keys). Then, type in:
M-x comment-region < RETURN > *OR* C-c C-c
Presto! The region is entirely commented out. This will be helpful when debugging your
code and testin complex programs. To undo the commenting, just type C-_
The file that you turn in must begin with a header block. A header is a block of comments placed at the very top of your programs (you'll notice that the top portion looks similar to that found on your HW's).
