About This Repository

Welcome to the Network Server Collection! 🎉
This repository contains multiple variations of a TCP client-server application implemented in C and C++. Each project explores a different approach to handling multiple clients and concurrency or specific purpuses (fot ex. calclator), all while adhering to clean and reusable object-oriented design principles.

Variations

1. Simple-Client-Server A simpler, single-client implementation showcasing the basics network socket programming in c.

2. Client-Server-Calculator A simpler, single-client implementation showcasing the basics network socket programming in c, which is a calculator with basic operations.

3. Client-Server-cpp-fork
   A process-based version where the server spawns a new process (fork) for each client. While this approach supports multiple clients, shared resources (like the server terminal) are not protected in this version.

4. Client-Server-cpp-threads
   A multithreaded version of the server where each client connection is handled by a separate thread. Synchronization is ensured using std::mutex, making it safe for shared resources like the server terminal.

Key Features Across All Projects

• Object-Oriented Design: Classes like Net::Socket and Net::InetSocketAddress encapsulate low-level networking functionality.
• TCP Communication: Send and receive messages between a client and server.
• Graceful Shutdown: Use the keywords to close a session cleanly.
• Port Reuse: Avoid port conflicts with SO_REUSEADDR.

Getting Started

Each project has its own directory with a detailed README and makefile. Pick a version, compile it, and enjoy! 🚀
