I) C: Expense Tracker

Features:

1. Input Validation: Ensures only valid input is accepted, such as positive expense amounts and valid date formats.
2. Dynamic Memory Allocation: Uses dynamic memory for handling an adjustable number of expenses.
3. File Persistence: Saves expenses to expenses.txt, allowing data to persist between sessions.
4. Date Validation: Verifies that the entered date follows the DD-MM-YYYY format.
5. Modular Design: Code is organized into smaller functions with clear responsibilities, improving readability and maintainability.
6. Search Functionality: Users can search expenses by category, date, or amount range.
7. Expense Editing and Deletion: Enables modification or deletion of specific expenses, offering flexibility in managing data.

III) Java: Weather Forecast

Features:

1. Real-Time Weather Information: Provides users with up-to-date weather data.
2. Secure Data Retrieval: Utilizes Java's HttpURLConnection to securely fetch weather information from external APIs.
3. OpenWeatherMap API Integration: Integrates with the OpenWeatherMap API to provide comprehensive weather details.

V) OS: Bank Simulation System

Features:

1. Bank Account Operations: Users can create accounts, deposit funds, withdraw money, transfer funds, and check balances.
2. Transaction Logging: Logs every transaction with timestamps to provide a detailed history.
3. Interest Application: Simulates interest calculation on account balances.
4. Account Deletion: Users can delete accounts by entering the account number.
5. Multi-Account Management: Supports managing multiple accounts within the system.
6. Customer Interaction: A text-based menu allows customers to perform various banking operations.
7. Real-Time Transaction History: Users can view transaction logs and track their financial activity.
8. Dynamic Account Creation: Allows for creating new accounts dynamically during runtime.
9. Balance Check: Users can check the current balance of their accounts.
10. Input Validation: Ensures the user provides valid input for different banking operations.

OS Principles Used:

1. Concurrency: Simulates concurrent access where multiple users can perform actions simultaneously.
2. Synchronization: Ensures safe access to shared resources, such as bank accounts, using locking mechanisms (mutex).
3. Atomicity: Ensures that transactions (deposit, withdrawal, transfer) either complete fully or fail, preserving system consistency.
4. Resource Management: Bank accounts are managed efficiently, ensuring no resource conflicts.
5. Memory Management: Dynamically allocates memory for bank accounts during runtime.
6. Input/Output Operations: Handles user inputs for transactions and outputs transaction logs and balances.
7. Error Handling: Manages errors like insufficient funds or invalid inputs.
8. Time Management: Tracks transaction timestamps, similar to scheduling in OS processes.
9. State Management: Tracks account state (balance, transaction history), similar to process state tracking in OS.
10. User Interaction: Prompts users for input and feedback, similar to interactive OS environments.
