🚗 RentACar Platform - Code Overview and Functionalities

Welcome to the RentACar Platform repository! 🚗💻 This system simulates a car rental service, showcasing key programming principles through a simple and user-friendly interface.

The RentACar Platform is a console-based project designed to illustrate key programming concepts such as Object-Oriented Programming (OOP) principles, including encapsulation, inheritance, and polymorphism. 🛠️📚 The system leverages classes to manage users and vehicles, implements data validation mechanisms, and utilizes collections for efficient data handling. It serves as a practical example for learning how to structure code, enforce data integrity, and create dynamic user interactions in a clean and modular way. ✨

🛠️ Core Components

📁 Namespaces Used

• using System;
• using System.Collections.Generic;
• using System.Linq;

These namespaces provide essential functionalities like console input/output, collections, and LINQ operations.

🚀 Main Functionality

Main() Method

• Purpose: Entry point of the application.
• Actions:
  1. Calls InsertCars() to populate the car list.
  2. Prints a welcome message via StartMessagePrint().
  3. Directs the user to select their role and functionalities with ChooseFunction().

🏎️ Car Initialization

InsertCars() Method

• Purpose: Creates a list of 10 randomly generated cars with properties:
  • Brand, Model, Color, Year, Price, Availability.
• Details:
  • Uses Random to select random values from predefined arrays.
  • Each car is added to the cars list.

👥 User Management

ChooseUserType()

• Purpose: Differentiates between Admin and Regular User roles.
• Options:
  1. Register as a User.
  2. Register as an Admin (isAdmin = true).

RegisterUser()

• Purpose: Collects user details and initializes a new user profile.
• Details:
  • Prompts for name, password, and money.
  • Stores user information in the currentUser variable.

📜 Menu and Functionalities

DisplayMenu() and PrintFunctionsMenu()

• Purpose: Displays menu options for users or admins.
• Options:
  • Admin:
    1. Add/Delete cars.
    2. View or modify car details.
    3. Exit.
  • User:
    1. Rent/Return cars.
    2. View available cars.
    3. Calculate rent prices.

🔑 Admin Functionalities

Admin Actions

• Add a Car: Adds a new car with user-provided details.
• Delete a Car: Removes a car by its brand and model.
• View All Cars: Lists all cars in the system.
• Modify Car Details: Changes attributes like brand, model, price, etc.

🤝 User Functionalities

User Actions

• Rent a Car: Deducts the rental cost from user balance and marks the car as unavailable.
• Return a Car: Returns a car and marks it as available.
• Calculate Rent Price: Displays the cost for renting a car for a specified duration.
• View Available Cars: Lists all cars currently available for rent.

📦 Core Classes

BaseUser

• Purpose: Common functionality for User and Admin.
• Key Methods:
  • ViewAvailableCars(): Displays all available cars.
  • CheckIndexIsValid(): Ensures valid indices for cars.
  • IsCarAlreadyInTheSystem(): Prevents duplicate car entries.
  • FindCarIndex(): Finds a car by brand and model.

User (Inherits BaseUser)

• Attributes:
  • Name, Password, Money.
• Key Methods:
  • RentACar(): Handles car rental logic.
  • ReturnACar(): Manages car return functionality.
  • CalculatePrice(): Estimates the total rent cost.

Admin (Inherits BaseUser)

• Key Methods:
  • AddCar(): Adds a car to the system.
  • DeleteCar(): Removes a specific car.
  • ChangeCarDetails(): Updates car attributes.

Car

• Attributes:
  • Brand, Model, Color, Year, Price, Availability.
• Purpose: Represents a car entity in the system.

🏁 Exit Handling

Environment.Exit(0)

• Graceful exit from the application when the user chooses option 99.

📌 Highlights

• Role-Based Access: Separate menus and functionalities for admins and users.
• Robust Input Handling: Ensures valid user input with retries.
• Data Management: Maintains a dynamic list of cars with search and validation features.

✨ Future Improvements

• 🔒 Enhance security with encrypted passwords.
• 📈 Add a reporting system for rented cars.
• 🌐 Implement a GUI for a better user experience.

🛠 Technologies Used

• C# .NET: For backend logic and OOP implementation 🖥️
• Visual Studio: IDE used for development 👨‍💻
• Lists: For storing user accounts, transactions, and loans 📋

🎓 Credits

This project is based on the "RentACar Platform" exercise created by Mario Zahariev for Python developers. However, I adapted the task and implemented it in C#. You can view the original task here.

Special thanks to Mario Zahariev for providing a great foundational exercise.
