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 know more about any specific technique?

Can you explain how thread pools work?

Sure! A thread pool is a collection of pre-initialized threads that can be reused to perform multiple tasks, reducing the overhead of thread creation. It helps manage the number of concurrent threads efficiently.

What are futures and promises?

Futures and promises are synchronization primitives that allow you to retrieve a value from a thread that may not have completed yet. A promise is used to set a value, while a future is used to retrieve it.

How do I use condition variables?

Condition variables are used for signaling between threads. They allow one thread to wait until a condition is met, while another thread can notify it when the condition changes. You typically use them with a mutex.

Can you give an example of using a condition variable?

Certainly! Here's a simple example: a producer-consumer scenario where the producer waits if the buffer is full and the consumer waits if it's empty, using a condition variable to signal when items are added or removed.
