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:

- Write code in C# You must create parts of a small application that allows the user to manage the information on items for sale at a local store. The system must allow a user to add, delete and search for items. The system can hold a maximum of 10000 items. The class definition for an Item is given in the UML diagram below Note: getInfo() returns a string containing ALL of the state information neatly organized. Part 1: Create a class based on the specification above. Reminder: – means private and + means public. Part 2: a) Write a function/method called “addItem” that takes: An array of items The number of items in the array An integer representing a barcode A string representing the name of an item A string representing the description of an item A double value representing the price The function must create and add the item to the array if there is space. The function must return “true” if the addition was successful and “false” otherwise. b) Write a…Fill-in-the-Blank It is considered good programming practice to store the declaration for a class, its function definitions, and the client program that uses the class in __________________ files.Fill-in-the-Blank If you were writing a class declaration for a class named Canine and wanted to place it in its own file, what should you name the file? ___________________

It has the following grading scheme:3 quizzes 20 points each 20%Mid term 100 points 30%Final 100 points 50%Based on the total grade of any student for the course, the letter grade of each student can becomputed as follows:Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and anygrade below 60 is an F.This class needs to have some member variables. The first name, last name, the Z-number, thegrades, the total grade and final letter grade are all considered to be private member variablesof this class.The class should also have the following public member functions/procedural attributes that canbring the objects (students of the class) to life and give them some…Write code program using java languge for E-TechComputer store in Oman sells different electronics products such as Computers, Laptops and accessories. The store Management requires an automated software to keep track of items in stock and prices. You as a software designer and developer are asked to develop a system for the store. The first task you should carry out is to design and code a class related to stocked Items. You can name this class as Item_in_Stock. The class should consist of the following: A data member Item_code to store an item code e.g, C15, a data member to store item name, a data member to store item description, a data member to store quantity of items in stock and a data member item_price to store price of an item. You must use the appropriate data types and access specifier for each data member. Class should have a constructor that initialises class objects with specified item_code, quantity and price of items. Getter and setters methods for all the data…In C++ Q1.) Write a Review class that has: • These private data members: • string user: ID of the user • string item: ID of the item • double paid: the price of the item that the user buys • double rating: the rating that the user gives to the item • string review: the review content that the user gives to the item • These public member functions: • A default constructor to set all instance variables to a default value • A parameterized constructor (i.e., a constructor with arguments) to set all instance variables • A method for getting/setting the instance variables. • A method for printing the Review's information.
- Fill-in-the-Blank An operator may be __________ to work with a specific class.C++ requires that a copy constructor's parameter be a class object passed by _________________.PPM (Portable Pixmap) use three integers to represent a pixel – this means we can have images with RGB colors. You will create a Pixel class in C++ which has three attributes: red: int green: int blue: int You will create a default constructor that initializes those values to 255, and an overloaded constructor that takes user input to assign the values. The class will also have the following functions: changeRGB (): Takes in three integers to update the red, green, and blue attributes. Returns nothing. printRGB (): Takes in nothing. Prints the red, green, and blue attributes in order with a single space in-between each value. Returns nothing. You will then recreate the art program from Assignment 5 with the following changes: Instead of a 2D array of integers, you will create a 2D array of Pixel object. Don’t be scared! This is similar to creating a 2D array of strings. You will prompt for three color values instead of one – red, green, and blue. These must be stored in a Pixel…

The program should create two Motorcycle objects, and then set the Motorcycle’s speed, accelerate the Motorcycle object, and check its sidecar status. Instructions Open the file named Motorcycle.py. Create the Motorcycle class by deriving it from the Vehicle class. Call the parent class __init()__ method inside the Motorcycle class's __init()__ method. In theMotorcycle class, create an attribute named sidecar. Write a public set method to set the value for sidecar. Write a public get method to retrieve the value of sidecar. Write a public accelerate method. This method overrides the accelerate method inherited from the Vehicle class. Change the message in the accelerate method so the following is displayed when the Motorcycle tries to accelerate beyond its maximum speed: "This motorcycle cannot go that fast". Open the file named MyMotorcycleClassProgram.py. In the…Fill-in-the-Blank If you were writing the definitions for the Canine class member functions and wanted to place these in their own file, what should you name the file? ____________________
