代码： 全选

;; C/C++/Java mode
(defun my-c-mode-hook()
   ;; 将回车代替C-j的功能，换行的同时对齐
  (define-key c-mode-map [return] 'newline-and-indent)
  (interactive)
  ;; 设置C程序的对齐风格
  ;; (c-set-style "K&R")
  ;; 自动模式，在此种模式下当你键入{时，会自动根据你设置的对齐风格对齐
  ;; (c-toggle-auto-state)
  ;; 此模式下，当按Backspace时会删除最多的空格
  (c-toggle-hungry-state)
  ;; TAB键的宽度设置为8
  (setq c-basic-offset 4)
  ;; 在菜单中加入当前Buffer的函数索引
  (imenu-add-menubar-index)
  ;; 在状态条上显示当前光标在哪个函数体内部
  (which-function-mode)
)
(defun my-c++-mode-hook()
  (define-key c++-mode-map [return] 'newline-and-indent)

补充说明一下：
1 (interactive)放到每个函数的doc-string后面，以免byte-compile时出警告；
2 如果用了cedet（应该很多人都用了），开启了semantic的code-helper功能，(imenu-add-menubar-index)这句就多余了。
