hi Vincent,
by having:
   (ess-set-style 'C++ 'quiet)

in a mode hook, this will enforce users to the C++ indentation style,
despite the value of `ess-default-style'.

Not all your users may like that, so what I'd recommend instead is that
you have (or try):

(setq ess-default-style 'C++)
(add-hook 'ess-mode-hook
 	  '(lambda()
 	     (add-hook 'write-file-functions
                         (lambda ()
                          (ess-nuke-trailing-whitespace)))))


so that an end user can then put some other default in their .emacs
like:

(setq ess-default-style 'BSD)

and get 'the right thing'.

This should work even without the changes I added today.

Stephen
