Is there a specific reason why you are using an ancient, bug-ridden
compiler? CGAL 3.6 was the last release to support VS2005, but it will
be hard to find anyone that can still help you figure out things with
this set-up.

Did something get stripped out of your message here? This example
shouldn't show anything unless you enter some input.

A better description of your problem would be helpful.
