Compiler warnings (comparing signed and unsigned)

[acchow]

Running the make file produces no errors for me, but I get a slew of
warnings (comparing signed and unsigned). Should I fix these in my code,
or is it ok to have them? Seems pretty pedantic....

Be sure to submit your code (along with your Makefile) and then run a test
compile. This can be done by clicking on a button on the Assignments page
of the course site. This will send you an email with the results. If
there are any problems with compilation that need fixing, you will find
out through the email. Otherwise, it is safe to ignore these warnings.
