7. Create a source with VS Code hello.cpp file directory in cppProject
8. Add header file path index
In hello.cpp, you will find the header files that include the following line with a green wavy line represents the VS Code of C / C ++ plug-in header files could not find the appropriate path. Move your mouse over this line clicked, a prompt will appear yellow light bulb symbol, click on it, then click "Edit" includePath "setting" button will generate and open c_cpp_properties.json file, edit json file, add the C / C ++ path header files into it.
