I'm taking cs50 through edX, and received a grade of zero for initials.c in pset2 even though it is working correctly. I wasn't sure where or who to direct this question to.

Thx.

  • Hi, did you test your program with check50 first?, also notice that the grade can take up to three weeks to update. Here you can take a look to another question grade related cs50.stackexchange.com/questions/8990/…

  • I was unable to get check50 to work properly, so I check my work manually by seeing (on the gradebook page) the inputs it will be tested with and the outputs they expect to see. My initials.c program works properly, but I suspect I may have missed an invisible printable char which is causing it to fail. I haven't had time to look into it since I hit pset3. Thanks.

  • I am also getting strange results in check50. When I input the same values as check50 (Milo Banana, ROB), I get the correct results (MB, R), but the check50 returns the message: :( outputs "R" for "ROB" \ expected prompt for input, not output of "Please enter your name :" I have run update50, and the issue remains.

  • I don't know if this is the correct place to post this question, is the same subject, slightly different. I have coded the initials pset and tested, it returned "ok". When I checked my grade today I've noticed that I was graded 11 of 100. Rechecked my code and in fact was wrong. I fixed the code and what I really want to know is: Will the grade be changed or it ill remain the first given?

My problem was corrected by commenting out my prompt for user input. This runs counter to the spec ("a program that prompts a user for their name"), but is consistent with the illustration.
