Setting up vim for C/C++

This post if about the changes that I make in the configuration of vim to use it as an editor for C/C++ Programs. Now first of all make a file named .vimrc in your home directory

$ touch .vimrc
And also make a directory named .vim in the very same folder i.e. your home directory

$ mkdir .vim
Now here is the link of the things that you have to put in the .vim directory.

http://www.vim.org/scripts/script.php?script_id=213

Download the cvim Zip file from the link and extract the contents to the .vim directory
$ tar zxvf cvim.zip .vim/
Now copy paste the following in the .vimrc file

" All system-wide defaults are set in $VIMRUNTIME/debian.vim (usually just
" /usr/share/vim/vimcurrent/debian.vim) and sourced by the call to :runtime
" you can find below.  If you wish to change any of those settings, you should
" do it in this file (/etc/vim/vimrc), since debian.vim will be overwritten
" everytime an upgrade of the vim packages is performed.  It is recommended to
" make changes after sourcing debian.vim since it alters the value of the
" 'compatible' option.

" This line should not be removed as it ensures that various options are
" properly set to work with the Vim-related packages available in Debian.
runtime! debian.vim

" Uncomment the next line to make Vim more Vi-compatible
" NOTE: debian.vim sets 'nocompatible'.  Setting 'compatible' changes numerous
" options, so any other options should be set AFTER setting 'compatible'.
"set compatible

" Vim5 and later versions support syntax highlighting. Uncommenting the next
" line enables syntax highlighting by default.
if has("syntax")
  syntax on
endif

" If using a dark background within the editing area and syntax highlighting
" turn on this option as well
"set background=dark

" Uncomment the following to have Vim jump to the last position when
" reopening a file
"if has("autocmd")
"  au BufReadPost * if line("'\"") > 1 && line("'\"") <= line("$") | exe "normal! g'\"" | endif
"endif

" Uncomment the following to have Vim load indentation rules and plugins
" according to the detected filetype.
"if has("autocmd")
"  filetype plugin indent on
"endif

" The following are commented out as they cause vim to behave a lot
" differently from regular Vi. They are highly recommended though.
"set showcmd " Show (partial) command in status line.
"set showmatch " Show matching brackets.
"set ignorecase " Do case insensitive matching
"set smartcase " Do smart case matching
"set incsearch " Incremental search
"set autowrite " Automatically save before commands like :next and :make
"set hidden             " Hide buffers when they are abandoned
"set mouse=a " Enable mouse usage (all modes)

" My Style
"set columns=70
set textwidth=70
set ruler
set nu
set shiftwidth=4
set autoindent
set smartindent
filetype plugin on
let g:C_SourceCodeExtensions = 'h cc cp cxx cpp CPP c++ C i ii Makefile'
set expandtab           " set tab to spaces
set tabstop=4           " set tab size = 4
set colorcolumn=70      " set column color to indicate not to extend 
                        " more than 72 chars

" Source a global configuration file if available
if filereadable("/etc/vim/vimrc.local")
  source /etc/vim/vimrc.local
endif
And now you are all set and done. Happy Coding.
