C++ Concurrency Projects (C++17)

This repository contains a collection of small but practical C++17 projects focused on multithreading, synchronization, and thread-safe data structures.
The goal is to demonstrate clean, maintainable, and production-style C++ code using standard library concurrency primitives.

These projects are intentionally lightweight, dependency-free, and written in a style commonly used in real-world backend systems.

Projects Overview

1. Thread Pool

A fixed-size thread pool implementation that:

• Manages a pool of worker threads
• Executes submitted tasks asynchronously
• Uses a task queue with proper synchronization

Concepts covered

• std::thread
• std::mutex, std::condition_variable
• Task queues
• RAII-based resource management

---

2. Producer–Consumer (Bounded Buffer)

A classic producer–consumer problem implementation with:

• A bounded shared buffer
• Proper blocking using condition variables
• Safe access to shared state

Concepts covered

• Mutex locking
• Condition variables
• Thread coordination
• Avoiding busy waiting

---

3. Concurrent LRU Cache

A thread-safe LRU (Least Recently Used) cache that:

• Supports concurrent get and put operations
• Maintains eviction order using a doubly linked list
• Ensures correctness under multi-threaded access

Concepts covered

• Thread-safe data structures
• Cache eviction policies
• Lock-based concurrency control
• STL containers (unordered_map, list)
