安装
在官网下载适合自己的安装包
准备好mingw64（可以自己在官网下载 或使用其他软件安装位置处的 比如DevC++，codeblocks）
安装后先汉化
打开下图的图标
搜索并下载安装图中标红扩展（其他扩展也可以根据需要安装）
下面就是要设置环境变量
一般是指在操作系统中用来指定操作系统运行环境的一些参数
右键我的电脑 点击属性
右侧高级系统设置
双击红色标记的path
选择新建 然后将 mingw64的绝对位置输进去（推荐C盘根目录 这种文件还不放在C盘 能放哪？）
接下来选择一个盘下的文件夹存放code（绝对路径必须无中文）
这个绝对路径可以在打开文件夹后的资源管理器界面右上搜索栏右边的栏点击一下显示
选择对应文件夹
在该文件夹下新建文件夹（使用上面方式新建文件夹）名称为.vscode
在此文件夹下新建四个文件 名称如下
里面的内容如下(有关路径需要自己调整 或者选择和作者一样的路径存放)

错误调试
使用自动生成的tasks.json很可能会导致出现无法解析不存在的文件
解决方案：
在task.json里
把
“fileLocation”: [“relative”, “${workspaceRoot}”],
改为
“fileLocation”: [“relative”, “\”],
修复鼠标悬停信息提示
解决方案：
重装有关插件
输出的中文为乱码
解决方案：
将底部修改为如图所示 utf-8----->GBK
点击红色位置
