Because I can.t write chinese under ubuntu. so I use English.

I am a fresh man in ubuntu. I don't know how config the environment  for C++.

Search some material and says use emacs or vim to edit program. then use GCC to compile it.But when I install the vim or emacs .some problems occured.

Fist.

use these command to config

sudo apt-get install build-essential

sudo apt-get install vim

lichangh@ubuntu:~$ sudo apt-get install build-essential

Package vim is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'vim' has no installation candidate
lichangh@ubuntu:~$

when I use sudo apt-get update to update list ,also some error
