Answer / achal ubbott

OK! this is a set of questions. Let me see how far can I go.

1. destructor of a class can be called explicitly as
follows using the object of the class.

sample * p = new sample(/*some arguments*/);
p->~sample(); // explicit call;

3. correct order of destructor call is ~derived() and then
~base().
in case you haven't declared the destructor of base as
virtual then delete base; would cause problems.

cheers
