Flight Booking System (C++)

This is a small C++ project I made to practice using variable scopes, storage classes, and basic C++ programming. The program simulates a simple flight booking system where you can book and cancel flights, see booking history, and view some statistics.

Features

• FlightBooking: Create and cancel bookings with static tracking of seats and revenue.
• Booking History: Store and display booking details in a static vector for all flights.
• Statistics: Track active bookings, cancellations, total revenue, and average ticket price with formatted output.
• Flexible Pricing: Support custom ticket prices (e.g., $180.45, $270.99) with a default value ($366.89).
• Robust Logic: Prevent negative revenue and handle edge cases (e.g double-cancellation via bookingID check)

Storage Classes and Variable Scopes

• static: Used for things that should be shared by all bookings, like the total number of bookings, cancellations, and total revenue. This means every booking can update these numbers.
• mutable: Lets us change some values (like bookingID) even in functions that are supposed to be "read-only" (const methods).
• auto: Makes the code a bit easier to write by letting C++ figure out the type for us, especially when working with things like iterators or strings.
• Local variables: Regular variables that only exist inside a function, like when we calculate the average ticket price.

These helped me learn how to organize data and logic in a way that makes sense for a small project.

Purpose

I made this project to get better at using things like static variables, mutable variables, and auto in C++. It helped me understand how to organize code for a small system and how to use different storage classes and variable scopes.

How to Run

1. Make sure you have a C++ compiler (like g++) installed.
2. Compile the code:

   g++ src/mainFlightBookingReviewEx.cpp src/fns_FlightBookingReviewEx.cpp -I include -o flight
   

3. Run the program:

   ./flight
