In C, 'main' returns an int. What happens when you don't explicitly return a value, though? C99 provides a return value of 0, but C89... well, that's undefined, my favorite kind of behavior.

This is just another boring personal website. I don't have a Facebook, for obvious reasons. You can find me on Mastodon or LinkedIn (local résumé ). I also have a blog (because who doesn't), as well as, to the great amusement of my children, a distinct German accent.
