This project implements multiple hash tables to manage airline-related data efficiently. The hash tables cover planes, plane types, plane seats, passengers, reservations, flight legs, flight instances, airports, and pilots. Each hash table uses an appropriate hashing strategy and collision resolution method for optimal data access.

• PHash (Plane Hash Table) – Stores plane information using mid-square hashing and linear probing for collisions.
• PSHash (Plane Seats Hash Table) – Stores seat details for planes with chaining for collision handling.
• PTHash (Plane Type Hash Table) – Stores plane type attributes with double hashing for collisions.
• Passenger & Reservation Hash Tables – Uses modulo hashing with chaining to manage passenger and reservation data.
• Display, Insert, Update, and Select Operations – Each hash table supports basic CRUD operations and selective queries.

• main.cpp – Demonstrates usage of plane, plane seats, and plane type hash tables.
• PHash.h / PHash.cpp – Plane hash table implementation.
• PSHash.h / PSHash.cpp – PlaneSeats hash table implementation.
• PTHash.h / PTHash.cpp – PlaneType hash table implementation.
• passenger.h / passenger.cpp – Passenger hash table implementation.
• reservation.h / reservation.cpp – Reservation hash table implementation.
• makefile – Compiles all relevant .cpp files into the project2 executable.
• README.md – Project documentation.

1. Compile the project using the makefile:

   make

   This will generate the project2 executable.

2. Run the program:

   ./project2

3. Clean compiled files:

   make clean

   This removes all .o object files and the project2 executable.

• Ensure all CSV data files (DATA_Plane.CSV, DATA_PlaneSeats.CSV, Data_PlaneType.CSV, etc.) are located in the same directory as the executable for proper loading.
• Each hash table is initialized with a fixed size of 23, with collision strategies adapted per table type.
• The project demonstrates object-oriented design, file I/O, and different hashing strategies for practical airline data management.
