Answer 1

You're passing stat the name of the file, but it needs a path to the file. If you check the return value for stat, you'll see that it's only succeeding for . and .., because they exist in any directory.

Canonical answer: Do not ever try to understand the behavior of a program that blows through error conditions. As soon as it's even the tiniest bit mysterious (at the latest), add code to check the return values of all functions.
