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.

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...
