How can I effectively use thread pools in C++14?

In C++14, you can use the standard library's thread support along with a custom thread pool implementation. Would you like a code example?

Yes, please provide a simple code example.

Here's a basic thread pool implementation:

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

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

// Implementation details...

This sets up a thread pool where you can enqueue tasks to be executed by the threads.

What are the benefits of using a thread pool?

Using a thread pool can improve performance by reusing threads, reducing the overhead of thread creation and destruction. It also helps manage resources more efficiently.
