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 a unique form of class member that enables an object to store and retrieve data.
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.C++ Personal Information Class: Design a class that holds the following personal data: name, age, and phone number. Write appropriate accessor and mutator functions. Demonstrate the class by writing a program that creates three instances of it. One instance should hold your information, and the other two should hold your friend's or family member's information.Defining a class object is often called the _________ of a class.
- C++ Pet Class You are going to organize and show information about pets in a Pet Store using a Pet class. The Pet class You need to make a Pet class that holds the following information as private data members: the name of the pet (e.g. "Spot", "Fluffy", or any word a user enters) the type of pet (e.g. dog, cat, snake, hamster, or any word a user enters) level of hungriness of the pet (2 means hungry, 1 means content, 0 means full) Your class also needs to have the following functions: a default constructor that sets the pet to be a dog named Buddy, with level of hungriness being “content” a parameterized constructor to allow having any type of pet the order of the parameters is: name of the pet, type of pet, hungriness level a PrintInfo function that prints the info for the pet according to the sample output below a TimePasses function that increases the hungry level of the pet by one (unless its hungry level is already 2, meaning hungry). a FeedPet function that changes the…C++ Pet Class You are going to organize and show information about pets in a Pet Store using a Pet class.

Theme: Reloading operators. Task : Define the ROW class and define operations in it to add a row to a row above zero terminal rows, replace the substring with a row with a second row as an operator function. Perform specified operations on class objects.
- C# Language Create a class named Account with an instance variable named account_number. Make this class a member of the Accounts namespace.Account Class) Create an Account class that a bank might use to represent customers’ bank accounts. Include a data member of type intto represent the account balance. Provide a constructor that receives an initial balance and uses it to initialize the data member. Theconstructor should validate the initial balance to ensure that it’s greater than or equal to 0. If not, set the balance to 0 and display anerror message indicating that the initial balance was invalid. Provide three member functions. Member function credit should add anamount to the current balance. Member function debit should withdraw money from the Account and ensure that the debit amountdoes not exceed the Account’s balance. If it does, the balance should be left unchanged and the function should print a messageindicating "Debit amount exceeded account balance." Member function getBalance should return the current balance. Create a programthat creates two Account objects and tests the member functions…True/False: a member function in a class can access all of its class's member variables, but not if the variables are protected.
- True or FalseA base class reference variable can reference an object of any class that is derived from the base class.py You want to initialize parts of a class definition once at the time a class is defined, notwhen instances are created.Age calculation. You must use the object oriented programming for this problem. USE JAVA LANGUAGE (1) Create a class called Date that Includes three pieces of information as data members—a month (type int), a day (type int) and a year (type int). Have a constructor with three parameters to initialize the three data members. Call setters inside to initialize each attribute. Provide a set and a get method for each data member. Assume that the values provided for the year and day are correct, but ensure that the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a member function displayDate that displays the month, day and year separated by forward slashes (/). Provide a member function called calculateAge with three parameters that indicate a future date (represented as month, date, and year). Calculate one’s age based on one’s birth date and this future date. Inside the method simply print out one’s age in the format of how many years and how many days. Note…
