Actually you don't, because emacs by default indents the line when you
press ';'. ;-)

There might be a better way to do it, but you can accomplish what you
describe by putting this in your .emacs file:

(defadvice newline (after always-auto-indent)
  (indent-according-to-mode))
(ad-activate 'newline)

I'm personally at the point where I'm sometimes surprised when I
unconsciously press TAB in another editor and it inserts some
whitespace at the cursor instead of fixing my indentation.  If you've
really got a love for having the editor take care of your whitespace,
try this:

(c-toggle-auto-newline 1)
(c-toggle-hungry-state 1)
