The numbers seem to depend heavily on your environment, by the way:

  $ uname -m
  x86_64
  $ source /etc/os-release && echo $NAME
  Arch Linux
  $ echo '#include <iostream>' | g++ -E  -x c++ - | wc
    27336   59448  643240

Sure. Mine was macOS Sierra.

If your <stdio> is comparable to mine, that's still about 30 times more bytes that the compiler sees for C++ compared to C.
