How can I implement a thread pool in C++11?

To implement a thread pool in C++11, you can use the <thread> and <future> libraries. Start by creating a class that manages a collection of worker threads.

What should the worker threads do?

The worker threads should wait for tasks to be assigned to them, execute those tasks, and then return to waiting for more tasks.

How do I add tasks to the thread pool?

You can use a queue to store tasks and a condition variable to notify worker threads when new tasks are available.

Can you provide a simple code example?

Sure! Here's a basic outline:

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

class ThreadPool {
public:
    ThreadPool(size_t);
    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 further!
