A virtual function is called using a reference to a base class. Discuss if the function in base class is called or the function in the derived class and why?
Homework Answers
That's called polymorphism case 1) if the base class pointer is pointing to an object of the base class, then the function in the base class is called case 2) if the base class pointer is pointing to an object of the derived class, and if this virtual function is not overriden in the derived class, then the function in the base class is called case 3) if the base class pointer is pointing to an object of the derived class, and if this virtual function is overriden in the derived class, then the function in the derived class is called This is how polymorphism works..

Question 3: Q3 (Polymorphism & virtual function) a) Consider the class, derived class, and the virtual functions as shown in Display for Q3. Create a derived class (of Sale) called 'MailorderSale' having one private member variable called 'shipping charge'. It should have constructor function and virtual function 'bill' (this function adds shipping charge to the price). Define all these functions (no need of default constructors). b) In the main function, define one object of DiscountSale with (11,10) initial values and...

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.

If a derived class does not contain an overridden function for a pure virtual function in the base class, then objects of that derived class will not be allowed to be declared. Select one: O True O False

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...

A) Suppose you have a class called base which has been inherited by a class called derived. ( both classes have public, protected and private members ) What can a client of derived access within the class base ? What can the class derived access within the class base ? B) Suppose you have a class called more which has a private object of a class called simple. ( both classes have public, protected and private members...
