[Cs3] how to find out which standard your c++ compiler supports

[Mikhail Nesterenko]

CS3 students,

g++ -v -- help | grep std

Will list all supported standards. The g++ compiler on wasp/hornet is
version 8.5. The above command shows that it fully supports C++17 and
some selected features out of C++20.

Thanks,
