I have read that we should make sure that there are no users of moved-from object before moving it. I want to know why is that so ? Is the moved-from object destroyed after std::move() is called ? if not, What happens to the moved-from object after std::move() is called ?

It depends on how the result of std::move() is used. move itself does not do anything to the object.

Fair point. The statement `std::move(std::string("Hello"));` is legal, but does not move anything. – MSalters Nov 04 '14 at 15:07

The object is not destroyed, but it's in a state where the only thing still possible is to destroy it.

It has to be in a state that is safe to destruct, but, AFAIK, it does not have to be usable for anything else.
