How to add Cpp in polyglot?

[sskohli01]

A lot is us Competetive programmers have to solve multiple ques fast. Rather than creating multiple cpp files, it would be awesome if we can use the polyglot notebook for c++. Does it already supports cpp or any roadmap to include in future versions?

thanks, San

It does not support C++ and it's gonna be complicated to add.

Polyglot Notebooks has support for adding languages at runtime as child Jupyter kernels (which isn't specific to just Python and R), and there's a C++ Juptyer kernel: https://github.com/jupyter-xeus/xeus-cling

So this potentially works today, though I haven't tried it.
