Notebook Application (C#)

A simple console-based notebook application built using C#.

---

Features

• Add a new note
• List all notes
• Update an existing note
• Delete a note
• Automatically save notes to a file
• Load saved notes when the program starts

---

Technologies Used

• C#
• .NET Console Application
• File I/O (Read & Write)
• JSON Serialization (System.Text.Json)

---

How It Works

• The program stores notes in a List during runtime.
• When the user performs any operation (add, update, delete), the data is:
  1. Converted to JSON
  2. Saved into a file called notes.json
• When the program starts:
  1. It reads the notes.json file
  2. Converts JSON back to objects
  3. Loads the notes into memory
