What are the benefits of using a thread pool in C++?

Using a thread pool in C++ can improve performance by reusing threads, reducing overhead from thread creation, and managing resources efficiently.

How does a thread pool manage the number of threads?

A thread pool maintains a fixed number of threads and assigns tasks to them. If all threads are busy, new tasks wait in a queue until a thread becomes available.

Can you explain how to implement a simple thread pool in C++?

Sure! You can create a thread pool by defining a class that manages a vector of threads, a task queue, and synchronization mechanisms like mutexes and condition variables.

What are some common pitfalls when using thread pools?

Common pitfalls include not handling exceptions in threads, failing to manage the lifecycle of threads properly, and potential deadlocks if resources are not synchronized correctly.
