Nathan,
I'm learning c++ programming language by using "The complete c++
training course - second edition" (Harvey Deitel & Paul Deitel), hello
world is the first program in this book. I'm totally puzzled by this
complex language when I compile my first program. Is this book out of
date?
This post may off topic of FreeBSD, sorry to other people...
Regards,
David
