C++: Why destructor is defined as virtual in a derived class ?

I think it should be base class ?

In case, the derived class object ( accessed via the pointer to base class) is deleted, will result in undefined behaviour. (if the base destructor is not virtual). To avoid this, the base class destructor is made virtual.
Yeah , I agree with you. I believe that the query is related to destructor in base class.
