OOP Lab 04: Flight Reservation & Capacity Guard

Problem Objective

Implement a Flight class to manage airline bookings with private attributes: flightID (int), availableSeats (int, default 100), and fare (double, default 500.0).

Provide a constructor Flight(int id, int seats = 100, double flightFare = 500.0).

Implement bookTicket(int count = 1):

◦
Guard against negative booking counts or 0.
◦
Prevent overbooking: if count > availableSeats, display an error and reject the booking (return false).
◦
If valid, decrement availableSeats by count and return true.

Implement standalone function Flight compareFare(Flight f1, Flight f2) returning the Flight object with the cheaper (lower) fare.

In main(), instantiate flights, book tickets (testing both successful and overbooking scenarios), and find the cheaper flight.

Expected Terminal OutputStandard Out

[Flight 1] Flight ID: 401 | Open Seats: 50 | Fare: $450.00
[Flight 2] Flight ID: 402 | Open Seats: 100 | Fare: $320.00
[Flight 3] Flight ID: 403 | Open Seats: 5 | Fare: $600.00
[✓] Successfully booked 2 seat(s) on Flight 401
[!] Overbooking rejected for Flight 403: Requested 10, Available 5
Cheaper Flight: Flight ID 402 with fare $320.00

[✓] Flight class & compareFare verified (Time: 0.008s, Memory: 2.1 MB)

Execution Constraints

›Default availableSeats = 100, default fare = 500.0
›bookTicket must prevent negative counts and overbooking
›compareFare returns the flight with LOWER fare
