@First question :
As far as I can see, you've overridden the default destructor, so it doesn't really delete, only display your message. I really don't know how better to explain, other than to say that when you explicitly call the destructor, the object doesn't get deleted. I tried your code with some extras to test, and I found that I could access a member variable even after calling the destructor.

That said, no, you usually don't call the destructor explicitly.
