Smart File Compression System

Overview

The Smart File Compression System is a C++ application designed to compress files using a custom Huffman compression algorithm. The system reads a text file, computes character frequencies, builds a Huffman tree, generates Huffman codes, and compresses the file based on these codes. The result is a compressed binary file with reduced size.

Features

• Custom Huffman Compression: Implements Huffman coding to compress text files.
• File Handling: Handles file reading and writing with error checking.
• Compression Metrics: Provides information on the original and compressed file sizes.

Prerequisites

• C++ Compiler: Requires a C++11 compatible compiler (e.g., g++).
• Operating System: Tested on macOS.

Installation

1. Clone the Repository:

   git clone https://github.com/karan3691/smart-file-compression.git
   cd smart-file-compression

2. Compile the code:

   g++ -std=c++11 main.cpp -o main

Usage

• Prepare Your File: Ensure you have a text file named example.txt in the same directory as the executable.

• Run the Program:

  g++ -std=c++11 main.cpp -o main

  The program will output the results of the compression and display the sizes of the original and compressed files.

  Example Output

  Starting compression for file: example.txt
  File opened successfully.
  Character frequencies calculated.
  Priority queue created.
  Huffman Tree constructed.
  Huffman codes generated.
  Compression completed and file saved.
  Huffman compression completed for: example.txt
  Original file size: 39 bytes
  Compressed file size: 25 bytes
