Because the initialization of base class objects must not be destroyed by deleting object of derived class. That is base class destructor must not be called upon calling derived class destructor.

If object of derived class is created, then constructor of derived class is called automatically, and if base class constructor has same name, then it is called also.

Same scenario will be happened if Destructor of base class is not virtual.
