What are the different threading models in C++?

C++ supports several threading models, including the thread-per-task model, the thread pool model, and the event-driven model. Each has its own advantages and use cases.

Can you explain the thread-per-task model?

In the thread-per-task model, a new thread is created for each task. This model is simple and straightforward but can lead to high overhead if too many threads are created.

What about the thread pool model?

The thread pool model reuses a fixed number of threads to handle multiple tasks. This reduces the overhead of thread creation and destruction, making it more efficient for handling many short-lived tasks.

Are there any downsides to using a thread pool?

Yes, one downside is that if all threads in the pool are busy, new tasks must wait, which can lead to delays. Additionally, managing the pool can add complexity.
