ubuntu下使用Vim学习C++

安装

开发环境：

　　系统：ubuntu 16.04LTS。

　　工具：Vim7.4

　　编译，链接，运行：g++

　　现在贴上Vim的安装命令：
　　

sudo apt-get install vim-gtk
//or 
sudo apt-get install vim

简易配置

sudo vim /etc/vim/vimrc

imput this in the last columns

这里写代码片

set nu                           // 在左侧行号
set tabstop                  //tab 长度设置为 4
set nobackup               //覆盖文件时不备份
"set smartindent 
set cursorline               //突出显示当前行
set ruler                       //在右下角显示光标位置的状态行
set autoindent             //自动缩进

编译C++

vim demo.cpp
:wq
g++ ./demo.cpp
./a.out

配置Gvim/vim。

用于Gvim 或 Vim 配置文件的一键编译与运行函数（注：需要机器上安装了GCC才行， minGW）
本代码只加入了对C/C++的编译与运行，如果要加入其语言的可以参考此代码加入即可
同时，本代码加入了对Windows下用Gvim编译UTF-8编码格式的源文件时中文乱码的解
决方法（也就是在编译选项中加入了 “-fexec-charset=gbk”）。
将上面的代码加入到_vimrc文件里即可
