So I was wold by a friend of mine that for FRC if programming in C++ we can’t use the STL and if that’s the case why is that the case? Also moving on from there if the STL isn’t allowed then aren’t the student’s missing out on real C++??
You can absolutely use the STL. The roborio is just a Linux system building with a basically stock build of GCC. 2020 is going to be GCC 7.3, which allows even access to C++17 and many of the STL features that come with that.
