You perhaps want to use `customize-variable', which should do the right thing
about getting the setting, um, set. It prompts for the variable. You might
also find more comfort in M-x customize-group c RET
This probably isn't the best place to seek XEmacs specific advice, though, and
an XEmacs group is more likely to have qualified people to assist you.

I am not certain what about TABS you are missing, but the Emacs info manual,
accessible with C-h r, seems to cover this:
C-h F tab-to-tab-stop RET
Then, read that node, or visit the "Tab Stops" section below which talks about
how Emacs implements arbitrary tab stops in buffers.

Did you run through the tutorial, accessible with C-h t? Did that help, or
are your problems after you got to that point?
Do you know about customize, the easy way to configure Emacs?

Generally speaking, Emacs offers those features out of the box. The problem
is that the common ground between what you, I, and every other "normal
person"[1] needs is pretty small.
For example: I have not touched a c-mode setting in years, because I do next
to no C level development any longer. I have, however, invested substantial
effort into configuring Perl mode, which many people will not care about a
whit.

Mmmm. You may be stuck with the fact that Emacs, out of the box, doesn't do a
lot of the things that these other environments do by default. On the other
hand, Emacs doesn't *restrict* you to those things, either, which I prefer.
That said, Emacs is not the be-all and end-all of editors[2], so if you find
it easier to edit C++ in one of those IDEs you may just want to stick with
that.
I won't deny that Emacs has ...

... quite a learning curve, and can be difficult to follow. I think the
effort is rewarded, but you may not. Don't be afraid to say "this tool isn't
for me" — I did, regarding vi derivatives, because they don't work the way /I/
like to work, not because either I, or the tool, is defective.
Regards,
Daniel
Footnotes:
[1] Since, y'know, plenty of women use Emacs as well, so you shouldn't
exclude them from consideration.
[2] Well, I think it is, but opinions clearly vary as people seem to keep
using all those other editors as well, and liking them. :)

Good! But `setq' should work just as well (I think).

As a matter of interest, which version of XEmacs are you using (M-x
xemacs-version) and which version of CC Mode (M-x c-version)?

Yes. c-basic-offset, along with the other "style variables", becomes
buffer local when CC Mode is loaded. So you need to set c-basic-offset
_before_ CC Mode gets loaded. Are you setting c-basic-offset in your
init.el before anything (desktop, perhaps?) that loads CC Mode?

Would you please try starting XEmacs without your initialisation files
(? # xemacs -q --no-site-file), do the setting of c-basic-offset as you
described above, and then loading a C++ source file. Is c-basic-offset
now 2?
> Could you please enlight me here?
I suspect that you need to move the setting of c-basic-offset earlier in
your .init.el, as suggested above.

That's the way Emacs is. It's supremely easy to use, but maddeningly
difficult to learn. We've all been through this, so don't worry about
it. It's not just you. ;-)

There's the CC Mode manual. It's available at
<http://cc-mode.sf.net/html-manual/>, or if you prefer to download it
(e.g. in info format), <http://cc-mode.sf.net/manual/>.
Emacs in general, and CC Mode in particular, allow you to set things up
the way you want them, rather than imposing "helpful" things on you the
way many editors and GUIs do. The way you work best isn't the same as
how other people work. The trouble about this is that you _must_ spend
time on getting these things set up.

What features do you need? Some of them will just be a matter of
configuration, some might need a bit of hacking. I'll probably be able
to help you out.
By the way, I've directed replies to bug-cc-mode@gnu.org, the canonical
mailing list for these things.
