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 base class’s_________members are accessible within that base class and anywhere that the |
Step by step
Solved in 2 steps
- 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.Class members specified as________ are accessible only to member functions of the class and friend s of the class.Class members are accessed via the________ operator in conjunction with the name ofan object (or reference to an object) of the class or via the_____________ operator in conjunction with a pointer to an object of the class
- A base class’s____________ members are accessible within that base class and anywhere thatthe program has a handle to an object of that class or one of its derived classes.protected class members are only accessible inside the class (true/false) it’s possible to set the value of a private member variable of a class (true/false) setter and getter functions should be private (true/false)Problem Statement Design a Mother class that has the following member: • A virtual printInfo function that displays the class information which is the Class's name. Design a BabyA class that is derived from the Mother class. The BabyA class should have the following: • A printInfo function that overrides from the base class. The BabyA Design a BabyB class that is derived from the Mother class. The Babys class' print function should display only the class's name. class should have the following: • A print Info function that overrides from the base class. The BabyB class' print function should display only the class's name. Write a program that has an array of Mother pointers. The array elements should be initialized to Mother, BabyA, and Babys objects. The program should then step through the array with a loop and call each object's printInfo function. Partial Solution #include using namespace std; class Mother public: //declare a virtual function } { { { class } } void printInfo()…
- In order to extend a class, the new class should have access to all the data and inner workings of the parent class. True FalseAll of the following are true about a class EXCEPT: Oa function associated with a class is referred to as a subroutine. Oa class created in one source code file can be used in another source code file. Oa class is a blueprint for creating objects. Oa class can contains data, and methods to manipulate the data.Object composition is useful for creating a(n) _____relationship between two classes.
- Exercise 1-Account class • Design a class named Account that contains : • A private int data field named id for the account • A private double data field named balance for the account • A privet Date data field named dateCreated that stores the date when the account was created • A no-arg constructor that creates a default account • A constructor that creates an account with the specified id and initial balance • The getters (i.e., accessors) and setters (i.e., mutators) methods for id and balance • The getter method for dateCreated • A method named withdraw that withdraws a specified amount from the account • A method named deposit that deposits a specified amount to the accountProblem Statement:Define a class for a bank account that includes the following data members: Name of the depositor Account Number Type of account Balance amount in the accountThe class also contains the following member functions: A constructor to assign initial values Deposit function to deposit some amount. It should accept the amount asparameter. Withdraw function to withdraw an amount after checking the balance. Itshould accept the amount as parameter. Display function to display name and balance.Account class • Design a class named Account that contains:• A private int data field named id for the account• A private double data field named balance for the account• A private Date data field named dateCreated that stores the datewhen the account was created• A no-arg constructor that creates a default account• A constructor that creates an account with the specified id andinitial balance• The getters (i.e., accessors) and setters (i.e., mutators) methods forid and balance• The getter method for dateCreated• A method named withdraw that withdraws a specified amount fromthe account• A method named deposit that deposits a specified amount to the account TestAccount class• Write a test program named TestAccount that performsthe following:• Create an Account object with an account ID of 1122 and abalance of 20,000 S.R.• Use the withdraw method to withdraw 2,500 S.R.• Use the deposit method to deposit 3,000 S.R.• Print the balance and the date when this account was created
