OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

A(n) ____________ is one instance or variable of a class.
Some of the characteristics of a book are the title, author(s), publisher, ISBN, price, and year of publication. Design a class bookType that defines the book as an ADT. Each object of the class bookType can hold the following information about a book: title, up to four authors, publisher, ISBN, price, and number of copies in stock. To keep track of the number of authors, add another member variable. Include the member functions to perform the various operations on objects of type bookType. For example, the usual operations that can be performed on the title are to show the title, set the title, and check whether a title is the same as the actual title of the book. Similarly, the typical operations that can be performed on the number of copies in stock are to show the number of copies in stock, set the number of copies in stock, update the number of copies in stock, and return the number of copies in stock. Add similar operations for the publisher, ISBN, book price, and authors. Add the appropriate constructors and a destructor (if one is needed). Write the definitions of the member functions of the class bookType. Write a program that uses the class bookType and tests various operations on the objects of the class bookType. Declare an array of 100 components of type bookType. Some of the operations that you should perform are to search for a book by its title, search by ISBN, and update the number of copies of a book.
The technique of packaging an objects attributes into a cohesive unit that can be used as an undivided entity is ____________. a. inheritance b. encapsulation c. polymorphism d. interfacing
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.
Assume the definition of class houseType as given in Exercise 11. Answer the following questions. (1, 2, 3, 5, 7) a. Write the definition of the member function set so that private members are set according to the parameters. b. Write the definition of the member function print that prints the values of the data members. c. Write the definition of the constructor of the class houseType so that the private member variables are initialized to according to the parameters. d. Write a C++ statement that prints the value of the object newHouse. e. Write a C + + statement that declares an object house of type newHouse, and initializes the member variables of house to "Ranch", 3, 2, 2, 2005, 1300, 185000, and 3600.0, respectively. f. Which function members are accessors and which are mutators?
Assume the definition of class foodType as given in Exercise 6. Answer the following questions? (1, 2, 3, 5, 6) Write the definition of the member function set so that private members are set according to the parameters. The values of the int and double instance variables must be nonnegative. Write the definition of the member function print that prints the values of the data members. Write the definitions of the member functions getName, getcalories, getFat, getSugar, getCarbohydrate, getPotassium to return the values of the instance variable. Write the definition of the default constructor of the class foodType so that the private member variables are initialized to 0, 0. 0, 0, 0. 0, 0. 0, respectively. Write the definition of the constructor with parameters of the class foodType so that the private member variables are initialized according to the parameters. The values of the int and double instance variables must be nonnegative. Write a C + + statement that prints the value of the object fruit 2. Write a C++ statement that declares an object my Fruit of type foodType, and initializes the member variables of myFruit to Apple, 52, 0. 2, 10,13.8, and 148.0, respectively.
Mark the following statements as true or false. The member variables of a class must be of the same type. (1) The member functions of a class must be public. (2) A class can have more than one constructor. (5) A class can have more than one destructor. (5) Both constructors and destructors can have parameters. (5)
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.
(General math) a. Construct a class named Cartesian containing two double-precision data members named x and y, which will be used to store the x and y values of a point in rectangular coordinates. The member functions should include a constructor that initializes an object’s x and y values to 0 and functions to input and display an object’s x and y values. Additionally, include an assignment function that performs a memberwise assignment between two Cartesian objects. b. Include the class written for Exercise 2a in a working C++ program that creates and displays the values of two Cartesian objects; the second object is assigned the values of the first object.
Mark the following statements as true or false. All members of a struct must be of different types. (1) A struct is a definition, not a declaration. (1) A struct variable must be declared after the struct definition. (1) A struct member is accessed by using the operator :. (2) The only allowable operations on a struct are assignment and member selection. (2) Because a struct has a finite number of components, relational operations are allowed on a struct. (2) Some aggregate input/output operations are allowed on a struct variable. (2) A struct variable can be passed as a parameter either by value or by reference. (4) A function cannot return a value of the type struct. (4) An array can be a member of a struct. (6, 7) A member of a struct can be another struct. (8)
