What do you mean by "in order to"?
In Emacs mostly, and definitely in CC Mode, TAB indents the current line
according to its syntax. So, if you had this
main ()
{
printf ("Hello, Emacs!") ;
}
, and typed TAB on the the long line, it would indent it 4 spaces.
(Actually, typing that last ";" will have triggered automatic
indentation.)
If you want to insert an actual ASCII Tab character, the way to do this
is C-q Tab (that's hold down the control key, press q, leave the control
key, press TAB). You probably don't "want" to do this, however.
To insert a comment at the end of the current line, you could go there
and type "/* .... */". Better, just type M-; (that is, whilst holding
down the "meta" (alt) key, type ";").

There are lots of different values of "proper". :-) I'm guessing that
you want the indentation to be done with tabs rather than spaces, as far
as possible. For this, "customize" `indent-tab-mode' by clicking the
pertinent menu entry, or by typing M-x customize-variable<CR>.

You mean, I think, you want pressing the tab key to insert a tab
character (ASCII 9) into your buffer. First comment, you're probably
mistaken about this. ;-) You probably _don't_ want to "use" the tab
key this way (see below). However, if you did, the way would be to
"bind" the key to the `self-insert-command' command, by writing this into
your .emacs file (that's your primary initialisation file. If you
haven't got one yet, create it with C-x C-f, then type in "~/.emacs" (no,
don't type the double quote marks)):
(define-key c-mode-base-map "\C-i" 'self-insert-command)
(don't forget the tick).
However, if you do this, you'll lose the indentation feature of the tab
key. Question, why do you want to type TABs?
