I asked the same questions about three weeks ago, and got the following reply
from Andrew Cottrell:

"The C++ standard has changed slightly over the years and to get the program to
compile change the header include and add the namespace line as follows:-

#include <iostream>
using namespace std;"

This works just fine.
