a) it is version of derived class i.e., class D
b) it is version of base class i.e., class B
Explanaition:
Runtime polymorphism is achieved only through a pointer (or reference) of base class type. Also, a base class pointer can point to the objects of base class as well as to the objects of derived class. In above code, base class pointer ‘bPtr’ contains the address of object ‘D’ of derived class.
Late binding(Runtime) is done in accordance with the content of pointer (i.e. location pointed to by pointer) an Early binding(Compile time) is done according to the type of pointer, since print() function is declared with virtual keyword so it will be binded at run-time (output is print derived class as pointer is pointing to object of derived class ) and show() is non-virtual so it will be binded during compile time(output is show base class as pointer is of base type ).

Suppose the base class and the derived class each have a member function with the same signature. When you have a pointer to a base class object and call a function member through the pointer, discuss what determines which function is actually called—the base class member function or the derived-class function.

Pure Abstract Base Class Project. Define a class called BasicShape which will be a pure abstract class. The class will have one protected data member that will be a double called area. It will provide a function called getArea which should return the value of the data member area. It will also provide a function called calcArea which must be a pure virtual function. Define a class called Circle. It should be a derived class of the BasicShape class. This...

Question 6 Consider a case of single inheritance where Landline phone is a base class and Mobile phone is the derived class. Both the classes are as follow: (a) Landline: It has subscriber name and number as data members. The member functions are to provide the features of calling on a subscriber's number and receiving a call Void call (int sub_number) Void receivel (b) Mobile: Apart from inheriting the features of a Landline phone, it provides...

The vector should be able to store objects that belong to the Plant class or the Flower class. Create a function called PrintVector(), that uses the PrintInfo() functions defined in the respective classes and prints each element in myGarden. The program should read plants or flowers from input (ending with -1), adding each Plant or Flower to...
