How to make the C++ syntax prompt in vim compatible with C++11

Question

In situations like the picture above, a prompt will appear every time you use the new features of C++11.
How can I make vim's syntax prompts compatible with C++11?
Is this prompt function built-in or a plug-in function?
Plug-in, I installed YCM.
