- Objective: The main objective of this assignment is checking the students’ ability to work with ADTs. In this week's assignment, you will be writing the interface of an ADT in order to conform to the requirements of a larger application. Description: A car rental company needs to keep extensive records to run their operation correctly. Not only does a company need to keep track of their customers, but it is also imperative to keep good records on employees. Keeping track of what car a customer is driving is a good example of a record. In addition, many times, cars need to be transported between locations of a company. If a staff member is moving a car, it is important to know which staff members are moving certain cars. Suppose Old Dominion University wanted to create a car rental company called ODU rentals. This company has employed you to keep records for the company. The company is confident you will succeed in creating a large scale record system, but they would like you to prove…give An application that notifies the user when the stock price of a specific company changes could be an example of a watcher design.and go over several benefits of using the watcher pattern in the session design pattern.give An application that notifies the user when the stock price of a specific company changes could be an example of a watcher design.and go over several benefits of using the watcher pattern in the session design pattern.Scenario: Mr. X works in a large consulting company with multiple operations. Mr. X is a Software engineer who has recently developed an application which helps users keep track of medical information, doctor’s appointments, and prescriptions. Information about the user is stored in this application, including what prescriptions they are taking and how frequently they schedule doctor’s appointments. As the developers of the application, X and his software development team have access to this information. The application is in use by thousands of users. The marketing department of X’s company requests that X supplies them with customer-specific information so they can better target advertisements and other application suggestions to the users. X understands that he is part of a company, but also feels that the privacy of the application users should be protected. Additionally, X feels that as a software engineer, he should be responsible to those who use his technology. Analyze the…

- Task 4: The InstantRide User Satisfaction team is a core team for InstantRide, and they focus on increasing the customer satisfaction. They want to learn the travel time for each ride in the system. You need to return the USER_ID, and the TRAVEL_TIME column which is calculated using the TIMEDIFF function on the TRAVEL_END_TIME and the TRAVEL_START_TIME.An IS system allows you to input information about the products in which you are interested, the financial status of the companies that make these products as well as the information about the current market. It should be able to produce reports, such as a company contact list, a product list, and a financial report. You also need the system to answer queries about the number of product available. You will design one GUI user interface. Assume each input and output is worth 5 functional points, each database inquiry module is worth 15 functional points, and each GUI user interface is worth 15 functional points. Further assume that each functional points requires 300 lines of code in C++, Calculate the total function points, and line of code in C++.
