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

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
