✅ Console ToDo List (C++)

A simple task manager built in C++ that runs in the console and stores tasks in a text file.
Allows users to add, list, and mark tasks as complete. Great practice for file I/O, CLI interaction and logic structuring in C++.

You Choose:

📂 File Structure

• ToDoList.cpp
  
• example.txt ← generated automatically

🧹 Possible Improvements

• Refactor into multiple source files (TaskManager.cpp, main.cpp)

• Store tasks in CSV or JSON format
  
• Improve update logic (rewrite file instead of line edits)
  
• Add timestamps and task categories
