Is it possible to destruct a static object or variable before the
program terminate?

Thanks

You can call the destructor explicitly, but it will be called again when the
program terminates, so no, I wouldn't advise you to do that.

If you have to, use something pointer-like and use new and delete for
explicit allocation/de-allocation.

E.g. a boost::scoped_ptr or a std::auto_ptr or even a boost:ptional.
(Doesn't use the heap.)

Possible, yes. Desirable, no. The object will be destroyed twice.

Maybe you want a singleton rather than a static object?

Singleton is still implemented using static variable, right? What is
the advantage of singleton than static variable?

*Please* don't quote signatures.

Not necessarily.

There are other ways of implementing a singleton, such as using an
object with a static pointer member.
