Casting from a base to a derived class requires a constructor to initialize the derived class members that aren't in the base class. The constructor initializes the new member variables of the derived class for the object being casted from the parent class. When casting from a base to a derived class, a constructor is needed to initialize the additional members that are not present in the base class. The constructor of the derived class is responsible for initializing those members.
