What are some advanced threading techniques in C++?

Advanced threading techniques in C++ include thread pools, futures and promises, and condition variables. Would you like to explore any of these in detail?

Can you explain thread pools?

Sure! A thread pool is a collection of pre-initialized threads that can be reused for executing tasks. This helps in managing the overhead of thread creation and destruction.

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

To implement a thread pool in C++, you can use the C++11 standard library's <thread> and <mutex> for synchronization. You would typically create a class that manages a fixed number of threads and a queue of tasks.

What are futures and promises?

Futures and promises are a way to handle asynchronous operations in C++. A promise is a way to set a value that a future can retrieve later, allowing for synchronization between threads.

Can you give an example of using futures and promises?

Certainly! Here's a simple example: you create a promise, then launch a thread that sets the value of the promise. The future can then retrieve this value once it's ready.
