Ubuntu18.04之vim安装及配置
一、安装vim
命令行中输入：sudo apt-get install vim
(ps:它会显示让你输入密码，不过你输入的密码不会回显)
查看安装是否成功输入： vim -v
二、配置vim
第一步：在终端创建.vimrc文件命令为: $vi ~/.vimrc
(ps:表示手动设置一个配置文件 :vimrc , 这里把.vimrc文件创建在当前用户的根目录下)
第二步：在.vimrc文件中添加配置内容：
set shortmess=atI " 启动的时候不显示那个援助乌干达儿童的提示 winpos 5 5 " 设定窗口位置 set lines=40 columns=155 " 设定窗口大小 set nu " 显示行号 set go= " 不要图形按钮 syntax on " 语法高亮 autocmd InsertLeave * se nocul " 用浅色高亮当前行 autocmd InsertEnter * se cul " 用浅色高亮当前行 set showcmd " 输入的命令显示出来，看的清楚些 set statusline=%F%m%r%h%w\ [FORMAT=%{&ff}]\ [TYPE=%Y]\ [POS=%l,%v][%p%%]\ %{strftime(\"%d/%m/%y\ -\ %H:%M\")} "状态行显示的内容 set laststatus=1 " 启动显示状态行(1),总是显示状态行(2) set foldmethod=manual " 手动折叠 set background=dark "背景使用黑色 set nocompatible "去掉讨厌的有关vi一致性模式，避免以前版本的一些bug和局限 " 显示中文帮助 if version >= 603 set helplang=cn set encoding=utf-8 endif set fencs=utf-8,ucs-bom,shift-jis,gb18030,gbk,gb2312,cp936 set termencoding=utf-8 set encoding=utf-8 set fileencodings=ucs-bom,utf-8,cp936 set fileencoding=utf-8 autocmd BufReadPost * \ if line("'\"") > 0 && line("'\"") <= line("$") | \ exe "normal g'\"" | \ endif let mapleader="," nnoremap <space> : vnoremap <space> : nnoremap <C-h> <C-W>h nnoremap <C-j> <C-W>j nnoremap <C-k> <C-W>k nnoremap <C-l> <C-W>l inoremap <C-h> <Esc><C-W>h inoremap <C-j> <Esc><C-W>j inoremap <C-k> <Esc><C-W>k inoremap <C-l> <Esc><C-W>l let OpenDir=system("pwd") nmap <silent> <leader>cd :exe 'cd ' .

三、重启终端 创建、编写、编译、运行C、C++程序
(ps:以创建hello.cpp和hello.c为例)
1、在终端使用命令 $vi hello.c ($vi hello.cpp) 创建hello.c / hello.cpp文件，并进入vim界面；
2、键入i，进入输入模式
3、编写hello.c / hello.cpp程序
4、先按Esc键退出输入模式；然后按 : 键，进入命令模式；输入wq表示保存并退出。
5、编译hello.c / hello.cpp
5.1、对于C程序：在终端使用命令 $gcc hello.c
5.2、对于C++程序：用$g++ hello.cpp可编译，编译后均生成a.out的可执行文件
6、在终端使用命令 $ ./a.out 表示运行程序
7、在终端显示“helloworld!”即成功
小坑点：
修改ubuntu18.04界面大小：
1、使用CTRL+alt+t打开终端
2、使用命令xrandr 查看相应的屏幕分辨率的相关参数
3、使用命令 xrandr -s 相应分辨率（如1916x889）即可改为相应的显示
