What programming language is Native Instruments Battery VSTi written in? - native instruments piano serial

As above. If your source of knowledge.

As is so programmed, reverbs, and in what language? I was told that most VST and VSTi are written in C, but I can not see, confirms this. Has anyone here the code of their own plugins for audio? In which languages are and why? Thank you all the best.
