The magic document is the CC Mode manual, chapter "Getting Started".

The variable you need to set is `c-basic-offset'.  Here's what this fine
manual says:

c-basic-offset
     This Lisp variable holds an integer, the number of columns CC Mode
     indents nested code.  To set this value to 6, customize
     `c-basic-offset' or put this into your `.emacs':

          (setq c-basic-offset 6)

If you can't get this working, come back again.

Best of luck!
