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

To implement a thread pool in C++, you can use the C++11 threading library. Start by creating a class that manages a collection of worker threads.

What are the key components I need for the thread pool?

The key components include a task queue, worker threads, and synchronization mechanisms like mutexes and condition variables.

How do I handle task submission and execution?

You can create a method to submit tasks to the queue and notify worker threads to pick up tasks when available.

Can you provide a simple code example?

Sure! Here's a basic example:

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

This sets up the structure for your thread pool.
