In Chapter 10, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extclockType from the class clockType by adding a member variable to store the time zone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class.
Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.
Chapter 10 defined the class circleType to implement the basic properties of a circle. (Add the function print to this class to output the radius, area, and circumference of a circle.) Now every cylinder has a base and height, where the base is a circle. Design a class cylinderType that can capture the properties of a cylinder and perform the usual operations on the cylinder. Derive this class from the class circleType designed in Chapter 10. Some of the operations that can be performed on a cylinder are as follows: calculate and print the volume, calculate and print the surface area, set the height, set the radius of the base, and set the center of the base. Also, write a program to test various operations on a cylinder.
Q3: Class called ( myclass) and an objects of this class called (obj1) and (obj2). This class contains two data members of type integer (a and b) with private access, and three member functions with public access: constructor to give valne to variables, and default constructor and show0 to display variables. Write a program to set and display the objects fields.

Design a class bookType that defines a book as a class. a. Each object of the class bookType will hold the following information about a book: title number of authors up to four authors publisher year published ISBN 13 (with dashes) price number of copies in stock (may be 0) b. Include the member functions to perform the various operations on objects of type bookType: Include individual get and set functions for all member variables. c. Add a member function to update the number of copies in stock. d. Add the appropriate constructors and a destructor (if one is needed). Ensure a default constructor is coded and the constructor initializes all data members. Remember, an array of classes uses a default constructor only. e. ALL member variables must be private and accessed through member functions. The main client program CANNOT access the variables directly. f. Ensure the class declaration and class implementation files are in separate header and code (.cpp) files. This assignment will…
