Check50 fails but my code works! [duplicate]

Question

I have done my pset2 but my code fails check50 even though the code is correct and encrypts the text correctly. Here is the check50 output:

:) caesar.c exists
:) caesar.c compiles
:( encrypts "a" as "b" using 1 as key
   \ expected prompt for input, not output of "Your Key is:1\nPlease provide me with t..."
:( encrypts "barfoo" as "yxocll" using 23 as key
   \ expected prompt for input, not output of "Your Key is:23\nPlease provide me with ..."
:( encrypts "BARFOO" as "EDUIRR" using 3 as key
   \ expected prompt for input, not output of "Your Key is:3\nPlease provide me with t..."
:( encrypts "BaRFoo" as "FeVJss" using 4 as key
   \ expected prompt for input, not output of "Your Key is:4\nPlease provide me with t..."
:( encrypts "barfoo" as "onesbb" using 65 as key
   \ expected prompt for input, not output of "Your Key is:65\nPlease provide me with ..."
:( encrypts "world, say hello!" as "iadxp, emk tqxxa!" using 12 as key
   \ expected prompt for input, not output of "Your Key is:12\nPlease provide me with ..."
:) handles lack of argv[1]

How do I fix this problem?

This means that check50 was expecting your program to ask for a value, but instead your program printed out "Your key is: _". Comment out the line that prints out "Your key is" and it should be happy. Check50 is very picky about how your code works - while you can add extra printf statements for debugging, in the end you should only print out exactly what the pset description says.
