RAII-FileHandler

A modern C++ project demonstrating safe file handling using RAII (Resource Acquisition Is Initialization) and move semantics. This project ensures files are always closed properly and avoids common pitfalls with manual resource management.

🔧 Features

• Safe file opening and closing using RAII
• Prevents accidental copies with deleted copy constructors
• Efficient resource transfer with move semantics
• Custom file reading and writing methods
• Clean and modular project structure
• Makefile included for easy compilation

🚀 Getting Started

Prerequisites

• C++17 or above
• g++ or any modern C++ compiler
• make

Build the project

make

Run the executable

./main

Clean the build files

make clean

📖 Example

FileHandler file("data.txt", "a+");
file.write("Hello, RAII!");
FileHandler file2 = std::move(file);  // Transfer ownership
file2.rewind();
std::cout << file2.readline();
