The answer to that is definitely no, and definitely yes...
No, in the sense that the use of C++ on NetBeans 9 is not currently supported by Apache, and it is done at your own risk. NetBeans is currently being handed over from Oracle to Apache, and they haven't got to the C/C++ part yet. See What's Happened to My Favorite NetBeans Plugins? for more information.
Yes, in the sense that it is technically feasible to do it; the NetBeans 9 IDE allows you to use C/C++.
This is what you need to do:

The Name of the entry at the top of the list should be C/C++. If so, you have successfully made the plugin available:
Step 2 of 2: Install the C/C++ plugin.
Also, verify that you can now create a C/C++ project through the Project wizard:
