I have a big problem with pset2. I got 0.5 although both programs (vigenere and ceasar) work fine when I test them on my own, without check50. I got 100% for vigenere, and 0% for ceasar. Do you know what could have happened? I used update50. Every time I type correct ID for ceasar, after several seconds, "Invalid ID" appears. Help me, please.


Make sure you spell caesar correctly. You need to name your .c file caesar.c and then use that in check50 as well

check50 2014/x/pset2/caesar caesar.c

If you named it something else, then it will get a 0 grade because check50 (the grader) is expecting a file called caesar.c

  • I can't believe it - I mixed the letters :p Thank you very much :) – mimik00 Jul 22 '14 at 0:23
  • When you resubmit your code, make sure you submit both programs again (caesar.c and vigenere.c) as the submission is graded as a whole. in other words, don't just resubmit caesar. – curiouskiwi Jul 22 '14 at 0:24
  • I just resubmitted both programs. Hope, I'll get 1.0 :) – mimik00 Jul 22 '14 at 0:28
