CC Mode doesn't use standard-indent at all.  Sadly.  The great thing
about standards is that there're so many to chose from.  ;-)

The variables you need set are:
c-basic-offset           ; The size of an indentation - set to 4
indent-tabs-mode         ; Tells Emacs to use tabs rather than spaces -
                         ; set to t ("t" is Lisp's symbol for "true").
tab-width                ; How much space a tab character takes up on the
                         ; screen


Unfortunately, setting up CC Mode's "style variables" is too complicated.
If you don't manage to get this sorted now, it would be best if you could
supply "all the evidence" so that we can get it sorted out.  Believe me,
it WILL work.

So, next time round, please
(i) Post your .emacs file.
(ii) Post a (short) C++ source file which illustrates the problems.  Say
  exactly what is wrong with its indentation, and what you want it to
  look like.
(iii) Tell us EXACTLY what you do, after starting Emacs, to show the
  problem.
(iv) Post your CC Mode configuration here.  To get this, do C-c C-b
  (that's "control-c followed by control-b") in your C++ buffer, and cut
  and paste the information into your post.
