Hi,
you seem to code in C++ but because of the file-extension ".c" VS Code interprets it as plain C. "using" is not a keyword in C.
So your options are changing the language mode manually (symbol in the status bar stating "C" at the moment) or just use .cpp as filename extension.

Additionally I would advise you to add

__SIZE_TYPE__=long unsigned int

to your defines-section in _c_cpp_properties.json._ I used to have problems with auto-completion because size_t was not set properly.

Thanks to your help, the problem has been solved.
