Problem Statement: Develop an Inventory Management System (IMS) for a small retail business that allows the user to manage their product inventory. The system should enable the user to add, edit, update, and delete product information stored in a .csv file. The IMS should be console-based with a menu-driven interface. Requirements: 1. Classes and Objects: - Create a `Product` class with attributes such as `productID`, `productName`, `price`, `quantity`. - Implement a `InventoryManager` class that will handle operations like adding, editing, updating, and deleting products. - Use a `Main` class with the `main` method to run the program and display the menu. 2. File Operations: - Store product information in a .csv file named `inventory.csv`. - Implement methods in `InventoryManager` for reading and writing to the .csv file. 3. Menu-Driven Interface: - Implement a menu in the `Main` class that allows the user to select operations like Add, Edit, Update, Delete, and View Inventory. - Use…

Double Bubble For this exercise you need to create a Bubble class and construct two instances of the Bubble object. You will then take the two Bubble objects and combine them to create a new, larger combined Bubble object. This will be done using functions that take in these Bubble objects as parameters. The Bubble class contains one data member, radius_, and the corresponding accessor and mutator methods for radius_, GetRadius and SetRadius. Create a member function called CalculateVolume that computes for the volume of a bubble (sphere). Use the value 3.1415 for PI. Your main function has some skeleton code that asks the user for the radius of two bubbles. You will use this to create the two Bubble objects. You will create a CombineBubbles function that receives two references (two Bubble objects) and returns a Bubble object. Combining bubbles simply means creating a new Bubble object whose radius is the sum of the two Bubble objects' radii. Take note that the CombineBubbles function…
Copied distinguished correct. Shoud in class ruit class:First create a Fruit class that contains code common to all of the fruits.1. Fruit class has two data fields called color and seed.2. A private data field called season. 3. Three constants named SUMMER, WINTER, and AUTUMN to denote the season.4. The accessor and mutator methods for all three data fields.Apple class:Apple class is a subclass of Fruit. 1. Write a class called Apple which extends the Fruit class.2. Apples are produced in Winter season.3. Declare a data field called varieties. There are three varieties:a. Ciderb. Cookingc. Dessert 4.

Step 2 ShapesDemo.cs 1 using static System.Console; 2 class ShapesDemo 3 { static void Main() Create a Rectangle is a GeometricFigure 4 whose area is { // Your code here } 8 } determined by multiplying width by height. 7 Create a Square is a Rectangle in which the width and height are the same. Provide a constructor that accepts both height and width, forcing them to be equal if they are not. Provide a second constructor that accepts just one dimension and uses it for both height and width. The Square class uses the Rectangle 's ComputeArea() method. Create a Triangle is a GeometricFigure whose area is determined by multiplying the width by half the height. In the ShapesDemo class , after each object is created, pass it to a method that accepts a GeometricFigure argument in which the figure's data is displayed. Change some dimensions of some of the figures, and pass each to the display method again.
