reset c++ compiler

I accidentally typed "c++ something.cpp" when trying to compile a small program. It gave a couple of errors which looked unfamiliar to those given when just using the g++ command. Did I fuck something up? Ever since then I've been unable to compile code which I was previously able to compile when using the regular g++ command.

Did you recently install a new compiler? Like, say, Clang?

why did you write c++? Did you run some update command for your distro? I'm asking since that's probably why your system took a crap on its self, it often happens when linux.

Are you sure you wrote it in C++?  Maybe the source code is in Java or Javascript (both so similar to C++, only specialists can tell them apart)
