Suppose class Child is derived from class Parent that was in turn derived from class GrandParent. This question concerns order of calls to constructors and destructors for these three classes. Declare an object of class Child. We know that Child, Parent and GrandParent constructors are called. In what order are these constructors are called? When the time comes to destroy the class Child object, we know that Child, Parent and GrandParent destructors are called. In what order are these destructor called?

What will be an ideal response?
