I'm really trying to switch to emacs, but learning to setup the environment is a real pain. Everybody says it's worth it, so I just continue.
I want my c code to be implemented that way:
if(asdf)
{
asdr = 1;
}
Depending on the current standard (I know, don't get me started), could be:
if(asdf) {
asdr = 1;
}
I can't seem to change the indentation size from 2, it always looks like the GNU standard:
if(asdf)
{
asdr = 1;
}
, which I dislike. Here is what I have put in my .emacs:
; Warn in C for while();, if(x=0), ...
(global-cwarn-mode 1)
; no electric mode in c
(c-toggle-electric-state -1)
; indent the current line only if the cursor is at the beginning of the line
(setq-default c-tab-always-indent nil)
(setq-default c-indent-level 4)
(setq-default tab-width 4)
(setq-default indent-tabs-mode nil)
(setq-default c-basic-offset 4)
(setq-default c-basic-indent 4)
; These commands I read about on the web, but they don't work?
;(highlight-tabs)
;(highlight-trailing_whitespace)
This did not help, I have still the GNU indent. Anyone?

Your defaults are possibly being overridden by cc-mode's style feature.
Try initialising the default style like this:
(setq c-default-style '((java-mode . "java") (awk-mode . "awk") (other . "user")))
You should be able to paste the preceding line into your .emacs file, or customize the c-default-style variable. The default has (other "gnu") as the last element of the list, which means that all non-Java and non-awk files get the gnu style instead of what you set with setq. The special user style gets initialised from your manually-set style variables.
Another option is to pick one of the built-in styles instead of defining it yourself, or to create your own style using the c-add-style function. To do this, change "user" in the above command to the name of the style (as a string). Try the the stroustrup or python built-in styles to format if-statements how you want.
