Object Oriented Programming 1. Problem: Smart booking system Assume that you are creating a smart booking system, selling packages for the 2026 FIFA World Cup. Each package consists of three categories of goods: flights, hotels, and game tickets. The world cup 2026 is hosted by multiple cities. To simplify this task, we assume, that all the games are hosted in one city New York. The World cup lasts ten days from day 0 to day 9. Assume that you have negotiated with the airlines, hotels and game hosts for flight tickets, hotel rooms, and game tickets for the time period. Flight tickets: The full price for a one-way ticket between Sydney and New York is $2000. However, a discount can be given depending on the days of departure and arrival. The discount for a ticket from Sydney to New York is day*5%. The discount for a return ticket from New York to Sydney is (9-day)*5%. For instance, if you travel to New York on day 3 and return on day 8, the price of your tickets is: $2000*(1 3 * 5%) + $2000*(1- (9-8) * 5%) = $3600. The idea here is the closer to the end, the cheaper the fly-in tickets; the closer to the end, the dearer the fly-out tickets. It is assumed that the supply of flight tickets is unlimited. Hotel rooms: There are three different types of hotel rooms in the World cup Village: regular, bronze and gold. See the following table for the information about hotel rooms:

Types of rooms	Full price (per room per night)	Total rooms available (quota) each day	Discount
Regular	$150	25	No discount
Bronze	$220	20	20% if vacancy > 50%
Gold	$310	40	40% if vacancy > 50% 20% if vacancy > 20%

Hotel rooms are paid up-front. They are sold in vouchers. Each voucher is for a single day stay. For instance, if you travel to New York on day 3 and return on day 8, you will need to buy five hotel vouchers, one for each day. You could be allocated to different types of rooms in different days. Game tickets: There are a total of 15 games in 10 days. See the following table for detailed information:

No	Game day	Games	Ticket price	Quantity available (quota)
0	0	Opening	$2000	60
1	1	Round of 16-Group A	$170	45
2	1	Round of 16-Group B	$80	40
3	2	Round of 16-Group C	$80	45
4	2	Round of 16-Group D	$150	50
5	3	Round of 16-Group E	$480	45
6	3	Round of 16-Group F	$110	55
7	4	Round of 16-Group G	$130	45
8	4	Round of 16-Group H	$90	35
9	5	Quarter-finals-1	$80	20
10	5	Quarter-finals-2	$100	25
11	6	Semi-final	$300	35
12	7	Third place play-off	$100	45
13	8	Final	$100	30
14	9	Closing	$800	40

Travel package: A travel package contains one fly-in air ticket (from Sydney to New York), one fly-out ticket (from New York to Sydney), the hotel rooms and a set of game tickets. A package is feasible if it satisfies the following conditions: o The date of fly-in ticket is earlier than the date of fly-out ticket.

• The hotel rooms cover every night between the arrival and departure dates (not including the fly-out day).
• The hotel types should be the same or above the customers desired hotel type.
• All the game tickets should be in the dates between fly-in and fly-out (can be in the same day of arrival or departure; can also attend multiple games on the same day). One game, one ticket. o Only the games a customer requires can be included in the booking package to the customer. They can be less but each package must contain at least one game.
• The total costs should not exceed customers budget.

Booking systems profit: The booking system receives 5% profit from the sales of air tickets and hotel vouchers, and 15% from the sales of game tickets for each feasible package. There is no profit or loss on unsuccessful requirements. You will be given a list of customer requirements (randomly generated). Each customer requirement consists of:

• the budget of the customer (the upper limit the customer can pay)
• desired hotel type (regular, bronze, gold)
• a set of desired games to attend (up to 8 games)

The requirements are recorded in a text file. Download an example of requirement list from requirementList.txt. The format of each requirement in the text file is the following: budget, hotelType, [game₁, game₂, , game_n] Note that there is no specification of travel dates in customers requirements. By default, all travel package contains a return ticket, which cover all days for all the games and hotel stays. In other words, the days of games in the package are determined by the dates of travel and hotel stays. 2 Tasks and requirements In this assignment, you are required to write a C++ program that implements an booking system to create and sell travel packages to your potential customers. You will be given a list of customer requirements or randomly generate a list of customer requirements. Your program should try to find a feasible travel package for each customer based on the availability of hotel rooms, game tickets and customers budget. If you cannot find a feasible package for a customer, indicate that the requirement is rejected. A smart booking system should try to maximize its profit. You may translate your C++ into Java as an option of tasks, but a C++ implementation is mandatory. You will be provided with a base program, which contains a partial implementation of CustomerRequirement class and Ticket class, a head file with constant data, and a class driver. You are required to further extend the code to complete the tasks specified in the following.

2.1

Your program should include at least the following classes:

• a class called !"#$%&()*"+(&,$# that specifies a single requirement of a customer, containing the information of total budget, desired hotel types and a list of the games that the customer wants to attend (a partially implemented class has been included in the base code).
• a class called Ticket that specifies the common attributes of a ticket, including the type of ticket, valid date, full price and a discounted price (an implementation has been included in the base code).
• three classes: FlightTicket, HotelVoucher and GameTicket that extends the Ticket class using inheritance.
• a class called -./0.1 that specifies a booking package, which contains two flighttickets, a set of hotel vouchers (one for each day) and a set of game tickets.
• a class called 2%%0+,134#$&5 that takes a list of customer requirements, makes feasible travel packages for all the customers if possible and reports the outcome.

Requirement of implementation:

• Read the customer requirements from the provided text file and store the data in an array of CustomerRequirement objects.
• Output a report of all the feasible packages you produce and the list of rejected requirements into a text file.

As a pass level program,

• You may ignore the information of price discount, the restrictions on hotel rooms and game tickets. Simply assume that all prices are in full and the supply of rooms and game tickets is unlimited.
• However, the total cost of each package should not exceed the customers budget.

Note: You must implement all the required classes with the same names. However, you can create extra classes, or add more data items and member functions into classes whenever needed no matter for the basic functionalities or any advanced functionalities.

2.2

For students who seek credit or above, the calculation of packages will consider all aspects of a package, including price discounts, quota of hotel rooms and game tickets. However, for a credit only code, you do not have to optimize the booking systems profit.

2.3

Students who seek a distinction or above are required to create a class called requirementCreator that simulates customer requirements. The class should contain a member function that is able to create randomly 100-150 customer requirements. Each requireemnt consists of:

• Randomly creates a hotel category either regular, bronze or gold. o Randomly creates 1-10 different games (at most one for each game).
• Randomly generates a budget:
  • If the games include the opening ceremony, randomly generate the budget between 4500+150*number-of-games to 7500+150*number-of-games.
  • If the games include the closing ceremony, randomly generate the budget between 3800+150*number-of-games to 6800+150*number-of-games.
  • Otherwise, randomly generate the budget between 3250+150*number-ofgames to 5250+150*number-of-games.

The format of each requirement should be: budget, hotelType, [game1,game2, , gamen] Download an example of this list from the attachment. Your program should be able to read this file.
