概述：tasks.jason   launch.json settings.json一定要有，没有就别想跑。还有就是c 和c++配置有区别，切记，下文有说

1.安装扩展插件。

2.安装编译器，gcc.我用的是x86_64-8.1.0-release-win32-seh-rt_v6-rev0.7z ，直接解压缩到你喜欢的目录，然后在环境变量里面添加即可。

3.找个目录，创建一个c或者c++文件。

4.将目录打开，可以选择在c/c++文件目录下右键，vscode打开即可。然后可以在目录下看到.vscode文件夹，下面就是一些脚本，可以改。

5.c和c++不太一样。在tasks.json 里面（如果没有，自己创建，一共三个文件，在第7点里面）。

6.碰到的问题点。如果细致一点，按下操作，如果不想麻烦，直接在第7点，文章末尾三个文件直接创建和我一样的就行了。

然后拷贝我的tasks目录进去就好了。

7.我的三个目录的代码是
