Chapter 20, Problem 20.13E

(Package Inheritance Hierarchy) Use the Package inheritance hierarchy created in Exercise 19.9 to create a program that displays the address information and calculates the shipping costs for several Packages. The program should contain a vector of Package pointers to objects of classes TwoDayPackage and overnightPackage. Loop through the vector to process the Packages polymorphically. For each Package, invoke get functions to obtain the address information of the sender and the recipient, then print the two addresses as they would appear on mailing labels. Also, call each Package’s calculatecost member function and print the result. Keep track of the total shipping cost for all Packages in the vector, and display this total when the loop terminates.

(Combining Class Time and Class Date) Combine the modified Time class of Exercise 17.7and the modified Date class of Exercise 17.8 into one class called DateAndTime. (In Chapter 19, we’lldiscuss inheritance, which will enable us to accomplish this task quickly without modifying the existing class definitions.) Modify the tick function to call the nextDay function if the time increments into the next day. Modify functions printStandard and printUniversal to output the dateand time. Write a program to test the new class DateAndTime. Specifically, test incrementing thetime into the next day.
Write in C++ Language.   (Employee Record): Create a class named 'Staff' having the following members: Data members - Id – Name - Phone number – Address - AgeIt also has a function named 'printSalary' which prints the salary of the staff.Two classes 'Employee' and 'Officer' inherits the 'Staff' class. The 'Employee' and 'Officer' classes have data members 'Top Skill' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a officer by making an object of both of these classes and print the same.
(Richer Shape Hierarchy) The world of shapes is much richer than the shapes included inthe inheritance hierarchy of Fig. 19.3. Write down all the shapes you can think of—both two-dimensional and three-dimensional—and form them into a more complete Shape hierarchy with asmany levels as possible. Your hierarchy should have the base class Shape from which class TwoDimensionalShape and class ThreeDimensionalShape are derived. [Note: You do not need to write any codefor this exercise.] We’ll use this hierarchy in the exercises of Chapter 20 to process a set of distinctshapes as objects of base-class Shape. (This technique, called polymorphism, is the subject ofChapter 20.)
