My server.c works just fine, and it passes both checkpoints with check50 (there are 2 for this pset), but for some reason my grade is only 0.42, and for all the points of the second (final) checkpoint I get 0 credit. Any idea why this might be happening? Any help would be greatly appreciated!

  • I don't understand. Is this a new pset6? I don't know if I understand what is a checkpoint. It used to have a total of 17 happy faces that you can check with: check50 2015.fall.pset6.server2 server.c Oct 20, 2016 at 15:15

If you used any snippets in your code, please cite them!

I had a similar problem recently. If you are resubmitting anything at all as program_name(1).c or program_name(2).c, so forth, it will count that as 0, because the program looks for something named program_name.c, nothing else. Thus, it'd count it as a 0.

You can also contact Glenn Holloway at [email protected] and report the problem.
