📝 To-Do List Application

This is a simple command-line To-Do List application written in C++. It allows users to add tasks, mark tasks as completed, display tasks, sort tasks by priority, and save tasks to a file.

🚀 Features

• 📄 Display tasks: Users can view all tasks in the to-do list along with their descriptions, priorities, and due dates.
• 🔀 Sort tasks by priority: Users can sort tasks based on their priority levels (e.g., high, medium, low).
• 💾 Save tasks to a file: Users can save their to-do list to a file for future reference.

📋 Usage

1. Compile the program using a C++ compiler.
2. Run the compiled executable.
3. Follow the on-screen instructions to perform various actions such as adding tasks, completing tasks, displaying tasks, sorting tasks, saving tasks to a file, and exiting the application.

📝 Input Format

• When adding a task, users need to provide a description, priority level (e.g., high, medium, low), and due date (format: dd/mm/yyyy).
