Mastering C++: A Comprehensive Quiz Based on 'Thinking in C++'

Static objects are objects created within a class that can be accessed without creating an instance of the class. Static objects are destructed after main() exits or when exit() is called, because they have a longer lifetime than automatic objects, which are destructed when they go out of scope. B is incorrect because destructors for static objects are not called before main() enters. C is incorrect because the last instance of the object may not be the last to be destroyed. D is incorrect because destructors for static objects are automatically invoked when their lifespan ends.
