I used check50 to check my code and get it all right except "handle lack of argv[1]". It reports that"expected output, not an exit code of 1". Shouldn't I just return 1 when the argc is not 2 and argv[1] is not a positive integer?

- What does your program when you don't add any argument?supeindesu– supeindesu2015-01-16 14:50:17 +00:00Commented Jan 16, 2015 at 14:50

Try printing \n to stdout before returning 1.
If your program is executed without any command-line arguments or with more than one command-line argument, your program should yell at the user and then return a value of 1. From the error message, you can see that check50 expects output printf() and not just a return 1;.
