A sample .vimrc file

I use vim to write C/C++ and python programs. It is a very powerful editor for programmers. However before starting to use it, you need to have a customized .vimrc configure file to make vim work the way you like. The following is the .vimrc I'm currently using. It alone can meet my needs of editing C/C++ programs. I will talk about python later.

set nocompatible " use vim defaults
set ls=2 " allways show status line
set tabstop=4 " numbers of spaces of tab character
set shiftwidth=4 " numbers of spaces to (auto)indent
set smarttab

set scrolloff=3 " keep 3 lines when scrolling
set showcmd " display incomplete commands
set hlsearch " highlight searches
