Learn C the Hard Way – Lucky I already thought of that

Because I was remapping the keyboard, I left my terminal in root, and ended up creating an exercise as root. So later, I couldn’t amend it. Options were chown, chmod, or just leaving it there and not caring. Fortunately, I already had exercise expansions and extra credit as different files, so it didn’t affect me. However, pro-tip here; don’t do that.
