A default of 2 spaces?  UURRRRKKKK!!!   How horrible!

The variable you need to change is c-basic-offset, and it's documented in
the CC Mode manual on the page "Customizing Indentation".  How you would
go about setting it is on the page "Sample .emacs File".

First, why not check through your .emacs and find if it's getting set to
2 there?  If so, just change it.

Otherwise put something like this into your .emacs:

(defun prab-c++-hook ()
  (setq c-basic-offset 3))
(add-hook 'c++-mode-hook 'prab-c++-hook)

(_Don't_ forget the two quote marks in that last line.)
