C++ Debug

1. 如果右上角没有 run and debug button 记得把 setting 里 Intelli Sense Engine 改成 default，以及 Debug Shortcut 打开，Intelli Sense Mode 不能是 default
2. 如果 cpp 文件提示 header not found，那需要在 c_cpp_properties.json 中把 compilerPath，添加上
3. debug 的时候，默认他好像是会自动 build 的，当然也可以自己写 prelaunchtask，它的具体属性值需要和 build task 的 lable 一样；自己写的时候要注意下 cwd 这个属性。

其实大部分解决方案都可以从 vscode 官方文档里面找到

贴几个 .vscode 下面的配置文件记录一下。
