Pharmacy Management System

This project is a Pharmacy Management System implemented in C#, showcasing basic Object-Oriented Programming (OOP) principles. The system allows administrators to manage medicines and users to purchase medicines through a console-based application.

Features

1. Admin Functionality:

   • Add new medicines to the inventory.
   • Remove existing medicines.
   • View the list of available medicines.

2. User Functionality:

   • Search and purchase medicines.
   • View purchased medicines and their total cost at checkout.

3. Authentication System:

   • Role-based access (Admin/User) with authentication using predefined credentials.

4. Modular Design:

   • Encapsulation of logic within classes such as Medicine, Admin, User, and Login.
   • Clear separation of concerns for better code maintainability.

5. Interactive Console Interface:

   • User-friendly menu system for both Admins and Users.
   • Dynamic redirection and message display for enhanced user experience.

Object-Oriented Principles Used

1. Encapsulation:

   • Data and methods are encapsulated in classes like Medicine, Admin, User, and Login.

2. Inheritance:

   • While not directly applied here, the system architecture is designed for extensibility.

3. Modularity:

   • Each core functionality is encapsulated within its respective class.

4. Polymorphism:

   • The ToString method in the Medicine class is overridden for meaningful output formatting.

Installation and Usage

Prerequisites

• .NET Framework installed on your system.
• A C# IDE or text editor like Visual Studio or Visual Studio Code.

Running the Application

1. Clone or download the repository.
2. Open the project in your preferred IDE.
3. Compile and run the PharmacySystem application.
4. Follow the on-screen instructions to use Admin or User functionalities.

Credentials

• Admin Credentials:
  • Username: admin
  • Password: admin123
• User Credentials:
  • Username: user
  • Password: user123

Testing

The project includes basic unit testing for a major method:

• Example: Testing the addition of new medicines in the Admin class.

Running Unit Tests

1. Add a unit test project in your IDE.
2. Write tests for core methods like AddMedicine, Authenticate, or PurchaseMedicine.
3. Execute tests through the test explorer in your IDE.

Git Version Control

The project demonstrates proper version control practices with at least three commits:

1. Initial: Setting up the project structure and creating basic classes.
2. second commit: Implementing core functionalities (Admin/User operations, authentication, etc.).
3. last commit: Adding testing, documentation, and code cleanup.

Application Structure

• Classes:

  • Medicine: Represents a medicine with ID, name, price, and quantity.
  • Admin: Provides functionalities to manage medicines.
  • User: Allows users to purchase medicines and checkout.
  • Login: Handles authentication.
  • PharmacySystem: Main entry point for the application.

• Key Methods:

  • AddMedicine, RemoveMedicine (Admin functionalities).
  • PurchaseMedicine, CheckOut (User functionalities).
