Advanced Text Editor (C++ Console Application)

A feature-rich console-based text editor built in C++ that simulates core functionalities of real text editors such as insert, delete, undo/redo, cursor movement, word operations, and file handling.

---

📌 What is this project?

This project is a C++ text editor simulation that demonstrates how a real text editor works internally using data structures and algorithms.

It supports:

• Text insertion and deletion
• Cursor-based editing
• Undo and redo system
• Word-based deletion
• Search functionality
• File saving and loading
• Usage statistics tracking

⚙️ Features

✍️ Text Editing

• Insert text at cursor position
• Delete characters at cursor
• Delete custom range of text
• Delete full word at cursor

🔁 Undo / Redo System

• Undo last operations (insert/delete)
• Redo undone operations
• Stack-based implementation

📍 Cursor Control

• Move cursor to any position
• Real-time cursor display

🔍 Search

• Find all occurrences of a pattern
• Displays all matching positions

💾 File Handling

• Save text to file
• Load text from file
• Append text to existing file

📊 Statistics

• Number of insert operations
• Number of delete operations
• Undo/Redo counts
• Stack sizes

🧠 How it works (Concepts Used)

This project is built using core Data Structures & Algorithms concepts:

• stack (vector) → Undo/Redo system
• string manipulation → text editing
• file streams → file handling
• cursor logic → index-based editing
• search algorithm → substring search
• encapsulation (OOP) → class-based design
