ubuntu16.04下c编程环境配置及vim基本配置

配置编程环境：sudo apt-get install vim

                        sudo apt-get install g++

                        sudo apt-get install gdb

        

vim环境配置：set nocompatible                                       "vim比vi支持更多的功能，为了避免冲突，最好关闭兼容

                       set encoding=utf-8                                    "使用uhf-8编码格式

                       set showcmd                                             "显示输入命令

                       set clipboard=unnamed,unnamedplus      "可以实现从vim复制到剪贴板

                       set nu                                                        "显示当前行

                       set tabstop=4                                            "设置tab长度为4

                       set nobackup                                            "覆盖文件时不备份

                       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（行号和列号）

                       set autoindent                                           "自动缩进

                       set hlsearch                                              "显示高亮搜索

                       set history=100                                         "指令记录

                       set background=dark                                "设置背景颜色，有两种，dark 和 light ，dark为深色模式，light为浅色模式

                       set background=light                                 "设置背景颜色为浅色模式

                       syntax on                                                  "显示语法高亮

                       syntax enable                                            "显示语法高亮，同syntax on

vim的配置环境在文件vimrc中

以“只读”方式进入vimrc文件的命令：vim /etc/vim/vimrc

如果想要对vimrc文件进行写操作，必须使用sudo命令：sudo vim /etc/vim/vimrc
