Question

If in multiple inheritance, class C inherits class B, and Class B inherits class A. In which sequence are their destructors called if an object of class C was declared?

(a) ~C() then ~B() then ~A()

(b) ~B() then ~C() then ~A()

(c) ~A() then ~B() then ~C()

(d) ~C() then ~A() then ~B()

This question was addressed to me in exam.

The doubt is from Destructors in section Constructors and Destructors of Object Oriented Programming

Answer 1

Correct choice is (a) ~C() then ~B() then ~A()

The best I can explain: The destructors are always called in the reverse order of how the constructors were called. Here class A constructor would have been created first if Class C object is declared. Hence class A destructor is called at last.
