🔐 Login & Registration System (C++)

A console-based Login and Registration System developed in C++ to practice file handling, user authentication, and fundamental programming concepts. This project allows users to create an account and log in using stored credentials.

---

📌 Overview

This project was created to strengthen my understanding of C++ programming by implementing a simple authentication system. User information is stored using file handling, allowing registered users to log in with their saved credentials.

---

✨ Features

• User Registration
• User Login
• Credential Validation
• File-Based Data Storage
• Console-Based Interface
• Simple Menu-Driven Navigation

---

🛠️ Technologies Used

• C++
• Standard Template Library (STL)
• File Handling
• GCC/G++ Compiler
• Code::Blocks IDE

---

▶️ How to Run

Requirements

• Code::Blocks IDE (with the built-in GCC/G++ compiler)
• Windows Operating System

Steps

1. Download or clone this repository.
2. Open the project in Code::Blocks.
3. Make sure the project is using the GCC/G++ compiler included with Code::Blocks.
4. Build and run the project by pressing F9 or selecting Build → Run.
5. Follow the on-screen instructions to register a new account or log in.

Note: This project was developed and tested using Code::Blocks with the GCC/G++ compiler. It may require modifications to compile correctly in other IDEs or compilers.
