Auto Fill is a minor mode, so its local to every buffer.  But your
~/.emacs file is loaded in the *scratch* buffer.

And, auto-fill-mode's ARG must be positive (i.e. a number) to turn it on.

Good: Looking at its source, which is available from a hyperlink in its
doc string via `C-h f', (turn-on-auto-fill) is equivalent to
(auto-fill-mode 1).

Bad: Lisp symbols are case-sensitive.  `C-h v' easily confirms that
c-mode-hook is what you want:

(add-hook 'c-mode-hook 'turn-on-auto-fill)

See above.
