二 配置文件

c_cpp_properties.json

Ctrl + Shift + P，找到后点击，则会在工作目录中多出一个 .vscode 目录，进入，会有一个c_cpp_properties.json文件，我们就将要在这里面配置需要的头文件。
然后打开命令行，输入gcc -v -E -x c++ -
将上述得到的信息最下面的那些路径，添加到刚才vscode创建的c_cpp_properties.json中,如下所示，这样#include后面就不会出现红色波浪线了。

setting.json

问题描述：VS Code中出现“未定义标识符”，可以右键“转到声明”，但会一直出现红色提醒。

问题原因：VS Code intellisense不能自动找到需要的头文件路径，需要在用户设置中强制intellisense使用Tag Parser,递归方式检索头文件。

解决方式：找到工程对应的settings.json，并复制以下两个语句，在其中配置使用Tag Parser方式。

{
    "C_Cpp.intelliSenseEngineFallback": "Disabled", //需要添加的
    "C_Cpp.intelliSenseEngine": "Tag Parser",  //  需要添加的

}
