How to adapt IntelliJ IDEA to work with C/C++?

Question

C++ / C#

There is IntelliJ IDEA Ultimate 2016.3.3, I would like to use it for development in C / C ++. The search for plugins from the environment itself did not give any results, and when installing from an archive with a plugin downloaded from the JetBrains website, it gives the error "Plugin 'C/C++' is incompatible with this installation"
There is also Clion, but I would like to develop a multilingual project in one environment

Answer 1

No way.
