What are some advanced examples of C++ threading?

Can you provide some advanced examples of threading in C++?

Sure! One advanced example is using the std::thread class to create multiple threads that perform tasks concurrently. You can also use thread pools for better resource management.

What is a thread pool and how does it work?

A thread pool is a collection of pre-initialized threads that can be reused for executing tasks. This reduces the overhead of creating and destroying threads for each task.

Can you show me a code snippet for implementing a thread pool?

Certainly! Here's a simple example:

#include <iostream>
#include <thread>
#include <vector>
#include <queue>
#include <mutex>
#include <condition_variable>

class ThreadPool {
public:
    ThreadPool(size_t threads);
    template<class F>
    void enqueue(F&& f);
    ~ThreadPool();
private:
    std::vector<std::thread> workers;
    std::queue<std::function<void()>> tasks;
    std::mutex queue_mutex;
    std::condition_variable condition;
    bool stop;
};

This is just the beginning; you can expand it with more functionality!

What are some common pitfalls when using threads in C++?

Common pitfalls include race conditions, deadlocks, and improper synchronization. Always ensure that shared resources are properly managed to avoid these issues.
