call up an EDITOR using c++

[nano2]

I have the following uing a phyton script I would like to write this using c++

Any one got a good approach to do this using c++ classes

  import sys, tempfile, os
from subprocess import call

EDITOR = os.environ.get('EDITOR','vim')

initial_message = ""
  tempfile.write(initial_message)
  tempfile.flush()
  call([EDITOR, tempfile.name])
