伙伴们按照步骤来就可以成功，如果我写的不清楚，麻烦评论或者私信我。

一、打开vscode插件下载astyle

二、下载AStyle并配置环境

1、官网下载http://astyle.sourceforge.net/下载最新版AStyle，解压到本地文件夹。

点击之后等待下载跳转。

2、将解压的AStyle文件夹中bin文件夹路径添加到Windows的环境变量-系统变量-PATH。

（右键单击计算机，选择属性，搜索高级系统系统设置->高级，按步骤添加保存）

3、重启Windows，可以使环境变量更改起效。

三、ctrl+shift+p打开首选项设置，重启vscode生效。

加入以下格式化配置，

    "astyle.additional_languages": [
        "c",
        "cpp",
    ],
    "astyle.cmd_options": [
        "--style=ansi",//ansi,bsd,kr...,Brace Style Options
        "--convert-tabs",//-c, Convert tabs to the appropriate number of spaces.
        "--indent=spaces=4",//-s4, Indent using 4 spaces per indent.
        "--indent-switches",//-S, Indent 'switch' blocks, so that the inner 'case XXX:' headers are indented in relation to the switch block.
        "--indent-namespaces",//-N, Indent the contents of namespace blocks.
        "--indent-labels",//-L, Indent labels so that they appear one indent less than the current indentation level, rather than being flushed completely to the left (which is the default).
        "--indent-continuation=4",//-xt4, Indent continuation lines an additional 4 indents.
        "--min-conditional-indent=0",//-m0, no minimal indent.
        "--max-continuation-indent=40",//-M40, Indent a maximal 40 spaces in a continuation line, relative to the previous line.
        "--break-blocks" //-f, Insert empty lines around unrelated blocks, labels, classes, ...
    ],
