Answer / sagarika patra
When a destructor is declared as virtual in the base class
is known as virtul destructor.
Whenever any object of derived class of base type is freed
(using delete operator),the destructor of the derived class
is called and the memory allocated by derived class
variables are freed ,leaving the memory allocated by the
base class variables as unfreed.
Hence by declaring the base class destructor as
virtual,both the destructor will called in order.

Answer / riya piyush jain
In object-oriented programming, a destructor (sometimes
shortened to dtor) is a method which is automatically
invoked when the object is destroyed. Its main purpose is
to clean up and to free the resources which were acquired
by the object along its life cycle and unlink it from other
objects or resources invalidating any references in the
process. The use of destructors is key to the concept of
Resource Acquisition Is Initialization.
