| May 17, 2017 at 3:00 | comment | added | burningserenity | Thanks. I checked out the man page, and it says that errno will never be zero. Doesn't strtol return 0 on an error, though? That was what I had to work around by intentionally setting x to a number outside INT_MAX. This is intriguing, but I'm having a hard time wrapping my head around it. | |

You don't declare ERANGE or errno, they are part of errno.h. Run man errno for more information on what it is. With regards to the char* instead of char[], you are correct, my bad. String literals, unless declared as a char array, are immutable. I updated my answer.

| Apr 29, 2017 at 21:36 | comment | added | burningserenity | Also, why a char* and not a char array? I'm trying to do it that way, but I segfault when fgets tries to store the value from STDIN in the char*. | |
| Apr 29, 2017 at 15:09 | comment | added | burningserenity | I've never used errno.h before. How do I declare ERANGE? | |
