C Programming Projects Collection

A collection of C programming projects designed for beginners to learn and practice various programming concepts, from basic algorithms to network programming. Each project is self-contained and includes its own documentation and build system.

Projects Overview

1. SHA-512 Implementation

A cryptographic hash function implementation that demonstrates:

• Bit manipulation
• Complex algorithms
• Memory management
• File I/O operations

2. HTTP Server

A basic HTTP server implementation that covers:

• Socket programming
• HTTP protocol basics
• File serving
• Network communication

3. UDP Server-Client

A simple UDP-based communication system that teaches:

• UDP socket programming
• Client-server architecture
• Network protocols
• Message exchange

4. Port Scanner

A network diagnostic tool that demonstrates:

• TCP socket programming
• Network scanning techniques
• Error handling
• Command-line argument parsing

5. Ping Implementation

A custom ping utility that covers:

• ICMP protocol
• Raw socket programming
• Network diagnostics
• Time measurement

6. Tic-Tac-Toe

A classic game implementation that teaches:

• Multiplayer game server -Socket programming
• Game logic
• User input handling

7. Chat System

A real-time chat application that demonstrates:

• TCP socket programming
• Multi-threading
• Real-time communication
• Client-server architecture

8. Lexical Analyzer

A simple compiler front-end component that demonstrates:

• Tokenization of source code
• Parsing techniques
• Compiler design principles
• String manipulation

9. Arithmetic Compiler

A simple compiler that takes arithmetic expressions as input and generates assembly-like code:

• Lexical analysis (tokenization)
• Parsing and evaluation of expressions
• Assembly code generation
• Compiler construction fundamentals

10. Asteroid Game

A terminal-based game where you control a ship to avoid falling asteroids:

• Game state management
• User input handling
• Terminal-based graphics
• Real-time gameplay mechanics
• Simple collision detection

Getting Started

Each project in this repository is designed to be self-contained and includes:

• Source code
• Makefile or CMake configuration
• README with build and usage instructions
• Implementation details

To get started with any project:

1. Navigate to the project directory
2. Read the project's README.md
3. Follow the build instructions
4. Run the program as described

Prerequisites

• GCC compiler (for C projects)
• G++ compiler (for C++ projects)
• Make utility
• CMake (for C/C++ projects)
• Basic understanding of C/C++ programming
• For network projects: understanding of basic networking concepts

Recommended Book

To get started with C programming, I recommend this comprehensive book: The C Programming Language - A must-have resource for learning C programming fundamentals and best practices.

Learning Path

These projects are arranged in order of increasing complexity:

1. Start with Tic-Tac-Toe for basic programming concepts
2. Move to SHA-512 for algorithm implementation
3. Try the UDP Server-Client for basic networking
4. Progress to HTTP Server and Chat System for more complex networking
5. Finally, explore Port Scanner and Ping for advanced networking concepts

License

This project is open source and available for learning purposes.

Note

Some network-related projects (Port Scanner, Ping) require root/administrator privileges to run due to the use of raw sockets. Always use these tools responsibly and only on networks you have permission to test.
