thanks Fguy :)
I will have a look at this
Note that it is very old (1995) - pre any of the C++ standards (C++98, C++2003, C++2011, C++2014, c++2017)
It has things like void main() for instance, and char arrays because it was before std namespace and std::string.
So basically it is that far out of date it is fairly useless IMO. Probably better off reading the tutorial on this site.
That one slipped by me. Thanks for pointing that out. I try to avoid stuff that old.
