I am a C-programmer and am using v20.7. I would like to
change the default indentation level from "2" to "4" when
in C-mode. I have a couple manuals and both indicate to
change the emacs varibale "c-indent-level". However, neither
of these works in my .emacs file:
(setq c-indent-level 4)
(setq-default c-indent-level 4)
I would be *very* grateful if someone can suggest a solution.
thanks.

Emacs uses the cc-mode to fontify C files, and to indent to. Indentation
is based on the tab-width variable, which can be redifined for each
mode. The C structure's indentation is related to
c-basic-offset variable and an offset from. In order to have more
precise informations try M-x hell RET i RET C-s 'CC mode' or try this in
your .emacs file :
(setq tab-width 4)
;; this will make sure spaces are used instead of tabs
(setq indent-tabs-mode nil)
(setq c-tab-always-indent t)
;; Highlight matching parantheses
(show-paren-mode 1)
;;--------------------------
;; indentation
;; For more information : M-x info cc-mode
(setq c-comment-only-line-offset 0);; -1000 to have it at the
beginning of the line
(setq c-basic-offset 3);; general value for
indentation on wich every arg of the
;; c-set-offset will be based on
;; + mean c-basic-offset*1
(c-set-offset 'arglist-close 0);; 0 mean c-basic-offset*0
(c-set-offset 'arglist-intro '+);; function parameters
(c-set-offset 'substatement-open 0);; indentation of braces for
if, for, while
(c-set-offset 'substatement '+);; indentation of a statement
(each line of a function)
(c-set-offset 'case-label '+);; indentation for the label
in a switch-case structure
(c-set-offset 'defun-block-intro '+);; indentation of variable
def for a function (no tab)
(c-set-offset 'statement 0);; indentation of the
function's body (the first line
;; starts at this point)
;;--------------------------
The wright way to do this is to mak a new hook for the c-mode.
