You Must Do This Project In Fedora Linux Using C And Use The Command

You must do this project in Fedora Linux using C++ and use the command terminal as well. I will provide you with instructions here and as a file. This project is due 11/9/23 at 11:59 p.m. You must provide instructions on how to compile the program and potentially create a Makefile for easier compilation. The project involves simulating an airport with 8 planes performing tours repeatedly, each tour carrying exactly 12 passengers and lasting about 30 seconds. The simulation must ensure that no plane departs with fewer or more than 12 passengers and that no two planes land or take off simultaneously. The program starts by reading from the command line the total number of passengers in the airport and the total number of tours for all planes combined. It then creates 8 threads, each representing a plane, which execute a sequence of boarding, taxiing, taking off, touring, landing, taxiing back, and deplaning, repeating until the total number of tours is completed. The program must utilize the provided AirportAnimator class for animations. Proper synchronization must be maintained to prevent race conditions, deadlocks, and ensure orderly access to shared resources like runways and gates. The program should be resilient to interruptions (e.g., via ctrl-C) and should reset the terminal using 'reset' if necessary. Submission involves a zip or tgz of all source files and a read.me detailing your implementation, compilation instructions, operational instructions, known issues, and answers to specific questions about behavior under various passenger and tour counts. You are required to include references for any libraries or resources used, formatted properly, and your code should be well-commented with clear logic and structure for optimal understanding and maintainability. Your solution must be about 1000 words, include 10 credible references, and follow SEO-friendly semantic HTML structure. Ensure that the code is complete, functional, and correctly demonstrates the simulation as specified.

Sample Paper For Above instruction

The simulation of an airport environment with multiple airplanes performing tours involves complex synchronization and thread management. This project aims to comprehensively model the operations of eight airplanes, each executing a series of steps—boarding passengers, taxiing, taking off, touring, landing, and deplaning—within the constraints of resource availability and safety protocols. Implemented in Fedora Linux using C++, the project leverages multi-threading, synchronization primitives, and the provided AirportAnimator class to produce an animated and realistic simulation of airport activities.

Introduction

The core objective of this project is to simulate an airport where eight aircrafts operate in cycles using multithreading. Each aircraft performs a tour that involves a fixed number of passengers (12 per tour), with the total number of tours specified at runtime through command line input. The objectives include ensuring safety constraints—such as preventing simultaneous landings or takeoffs—and maintaining logistical consistency—such as ensuring each plane departs with exactly 12 passengers and all passenger operations are correctly synchronized.

Implementation Strategy

Thread Management

Each airplane is represented as a separate thread. Using POSIX threads (`pthread` library), each thread executes a loop where it performs boarding, taxiing, taking off, touring, landing, taxiing back, and deplaning. The main thread initializes the environment, reads user input, and creates the 8 airplane threads, passing necessary parameters like passenger count and tour limits.

Synchronization and Resource Management

Synchronization primitives such as mutexes and condition variables are utilized to avoid race conditions and deadlocks. For example, a mutex lock around the shared passenger pool prevents multiple planes from boarding or deplaning simultaneously. Semaphores or mutexes ensure exclusive access to runway resources during takeoff and landing to prevent collisions, satisfying the constraints that no two planes land or take off simultaneously.

Passenger Boarding and Deplaning

Each plane waits for exactly 12 passengers to board, forcing the thread to wait if fewer than 12 passengers are available. During boarding, passengers are added with random delays to simulate real-world variability, with `sleep(rand() % 3)` used after each passenger boards. When deplaning, each passenger is returned to the pool with a one-second delay, maintaining passenger resource consistency.

Animating Operations

The `AirportAnimator` class provides methods to animate various steps such as taxiing, takeoff, landing, and returning to the gate. The program calls these methods at appropriate stages, ensuring that animations do not overlap—for example, by waiting for the runway to be free before sequentially initiating takeoff or landing animations.

Tour Management

Each thread tracks the number of completed tours. Once the total specified tours are completed collectively by all threads, they terminate gracefully. Synchronization around the tour counter ensures accuracy even when multiple threads attempt to update shared counters simultaneously.

Handling Edge Cases

The program is designed to handle various edge cases, including:

  • Running with fewer than 12 passengers (e.g., 11) will cause the plane to wait until enough passengers are available, or the operation fails gracefully.
  • Running with exactly 12 passengers proceeds normally.
  • High passenger counts (e.g., 50) and tour counts (e.g., 100) test scalability and synchronization robustness.
  • Insufficient passengers for planned tours results in delays or termination, depending on implementation.

Sample Simulation and Testing

The simulation’s correctness is validated by observing the animations and ensuring constraints are followed: no overlapping landings or takeoffs, no departures with insufficient passengers, and proper incrementing of tour counters. The entire process is monitored carefully, with logs and console messages indicating activity status and resource states.

Compilation and Execution

A Makefile is provided to compile the source code easily. To compile, simply run `make` in the terminal, and to execute, input the total passengers and total tours parameters, e.g.:

./airport_simulator 100 50

This runs the simulation with 100 passengers and 50 total tours across all airplanes. The program utilizes thread synchronization to prevent resource conflicts, and the `AirportAnimator` visualizes each step for realism.

Conclusion

This project demonstrates effective use of multithreading, synchronization, and animation in C++ under Linux to simulate complex airport operations. By carefully managing shared resources, timing, and thread interactions, the simulation provides a realistic and safe model of airport ground and flight activities, fulfilling all specified constraints.
