Online Shopping System using Inheritance and Static Members Consider an online shopping system where members, including buyers and sellers, participate in buying and selling items. The system is designed using inheritance with a base class Member, and subclasses Buyer and Seller. The Member class maintains a unique member number, name, and amount in hand for each member. Both Buyer and Seller classes inherit from the Member class. The Seller class additionally maintains an item ID, item name, and item price. The system prompts the user to input details for a specified number of sellers and buyers. After inputting the details, the system allows a buyer to purchase an item from a seller by entering the item ID. The system then transfers the item price from the buyer's amount in hand to the seller's amount in hand. Furthermore, a static member totalMembers is implemented in the Member class to count the total number of members in the system. A static method displayTotalMembers() is provided to display the total number of members at the end of the program execution. Your task is to understand and analyze the provided Java code, identify the inheritance hierarchy and static members used, and explain how the code functions to maintain and operate the online shopping system. Highlight the interactions between buyers and sellers, the data stored for each member, and the utilization of static members to track the total number of members in the system.

online shopping cartYou are required to implement a simple C++ program for an online shopping cart using a single class. The program should include a class ShoppingCart to represent the shopping cart. Each item in the cart has a name, price, and quantity.The ShoppingCart class should have the following:Private attributes for an array of item names, an array of item prices, an array of item quantities, the total number of items in the cart, and a flag indicating whether the customer is an old customer.A member function addItem that takes the item name, price, and quantity as arguments and adds them to the cart.A member function calculateTotal that calculates the total price of all items in the cart, taking into account a 10% discount for old customers,using the this pointer.A member function displayCart that displays the information of all items in the cart, including the total price and any applicable discounts or rewards. Award 1 reward point for every Rs.10 spent. This function should also demonstrate the usage of functions with objects as arguments.Testcase1:Sample input:2  // no of itemsKeypad  // item1000   // price2  // quantityEarphone501Y  // Old customerOutput:Rs.1845.00184.5  // RewardTestcase 2:Sample Input:3Keyboard5001Mouse3001Monitor10001NOutput:Rs.1800.00180

Suppose you are building an online shopping platform “One Click Shopping”. On this platform, you can buy products from different available categories. To place an order, first, you have to register as a user and log in to complete the order. To place an order, select the product from the list and add it to the shopping cart. You can make payment through an online credit card or cash on delivery. After making payment your order will be completed. As a student of OOP (Object oriented programming) course you have to perform the following tasks using the above scenario. 1. Extract the Objects, their attributes (Characteristics), and behaviors (Operations). 2. Identify the generalization relationship and mention the parent and child classes

For a movie ticket booking system, write a program in Java to implement the process. Some persons need First class seating system (Option1). Another option is Second class seating system (Option 2). Implement this process using Polymorphism and inheritance. In the ‘First’ class get the inputs like movie name, Theater Name, Show Date, and Number of Seats. If the date is 2022-11-20 print the price as 500 else print the price as 1000 for each seat. In the ‘Second’ class Get the inputs like movie name, Theater Name, Show Date, and Number of Seats. Cost of each ticket is Rs.200. If theater name is “mnbjhrbjbj” apply coupon code and reduce Rs.500 from actual price. Print all the details as a report.

This question contains a brief UoD that provides contextual information regarding a system or organisation. You will need to create an Entity Relational (ER) diagram, or Extended Entity Relational (EER) diagram based on the UoD. If the UoD is unclear regarding specific aspects of the brief you may note assumptions on your ER diagram. However, please beware that your assumptions must not conflict with or violate any aspects of the UoD. On a large online retail platform, different users can log in using their unique identifiers and shop for various items. Each of these items comes with a unique identification code, name, price, and detailed description. Users, apart from their unique identifiers, also provide their name, email, and shipping address. These users can make multiple purchases on different dates, with each transaction assigned an identification code unique to the user, along with recording the date of the transaction and the total cost. Each transaction can consist of one or more items, and the same item could be part of various transactions made by the same or different users.
