I'm not familiar with Mint since I use Ubuntu, but it would surprise me
if Mint was different in this area than Ubuntu.

The C++ STL headers are prerequisites of the standard compiler package,
so it's also surprising to me that you wouldn't have them since you
have a C++ compiler, unless you installed it via some low-level package
rather than the standard compiler package.

All you should have to do to get a full C++ compiler environment based
on GCC is to run this:

  $ sudo apt install g++

and that should depend on (and thus import) all the other packages you
need to compile C++ code, including the STL headers like iostream.

That's certainly true on my Ubuntu 18.04 system.
