Operating Systems 2 – C++ Projects

Overview

This repository contains two multithreaded C++ projects developed as part of the Operating Systems 2 course. Both projects demonstrate key concepts in concurrent programming, thread synchronization, and resource management using modern C++.

📁 chat-server/

A multithreaded chat server and client application using TCP sockets (WinSock2 API).

• Handles multiple clients concurrently using std::thread.
• Synchronizes access to shared data (client list) using std::mutex.
• Features real-time message broadcasting and graceful shutdown support.
• Includes client support for message sending and receiving in parallel.

📁 dining-philosophers-problem/

An implementation of the classic Dining Philosophers Problem using threads and mutexes.

• Prevents deadlock and starvation through an ordered resource acquisition strategy.
• Simulates randomized thinking and eating times.
• Controlled termination via keyboard input listener.

Technologies Used

• C++17
• std::thread, std::mutex
• WinSock2 API (for chat server)

How to Run

Clone this repository:

git clone https://github.com/zuzdud/operating-systems-2-projects.git

Go to desired project directory:

cd dining-philosophers-problem
cd chat-server

Each project contains its own source files and build instructions. See the individual directories for compilation and execution steps.
