It looks like your include statements are missing what they are supposed
to include.  I made a guess that they should be as follows:

#include <iostream>
#include <conio.h>

It's been a decade since I last used any significant C++, but it appears
that conio.h is missing.  Googling around tells me that conio is a
Borland extension, so it probably won't be available by default for g++.
 There appears to be a SourceForge project to provide an equivalent for
MinGW however:

This blog post looks like it might also be helpful:

The file it instructs you to download doesn't work for me with g++ under
Cygwin though.  It causes the compiler to report a bunch of errors.
Maybe you'll have better luck.
