  2. I was expecting the mistakes in my code

http://docs.cs50.net/problems/hello/hello.html#code-check50-code clearly states that the command for calling check50 for hello is

check50 2016.hello hello.c

(assuming you're in the same directory as hello.c)

  • I folowed the link you provide and the command I find there is: 'check50 cs50/2017/x/hello' not 'check50 2016.hello hello.c' I'm having trouble checking for initials for pset 2

  • Maybe caching issues (my browser probably showed an older version). But there you are, you put a / where a space should be.
