VSCode调试Linux下C程序

win10下可以自己安装WSL，它是一个Linux系统，安装非常方便，直接在CMD中输入WSL即可进入Linux环境。
利用VSCode可以方便的使用WSL里面的GCC， GDB等C语言编译调试环境，省去了在windows下安装Cygwin这样
的软件的麻烦，还可以体验纯Linux环境下的C语言编程。

下面介绍配置方法：

Windows下程序目录：c:\users\myname\leetcode\CCPlus

WSL下程序目录：\home\myname\leetcode\CCPlus

在Windows的CCPlus目录下的.vscode目录下，保证有如下文件：

• c_cpp_properties.json 配置头文件包含
• launch.json 配置运行环境
• tasks.json 配置调试环境
• settings.json (可选)本工程的vscode自定义配置

c_cpp_properties.json：

注意把上面路径相关的替换成你自己的路径，这样就可以编译运行外加调试了。
调试的时候鼠标悬停在变量名称上可直接查看变量的值，和VS2017一样方便。
