What are semaphores and mutexes in programming?

Semaphores and mutexes are synchronization primitives used to manage access to shared resources in concurrent programming.

How do semaphores differ from mutexes?

Semaphores allow multiple threads to access a resource up to a limit, while mutexes provide exclusive access to a resource.

Can you give an example of when to use a semaphore?

Sure! Use a semaphore when you want to limit the number of threads accessing a resource, like a database connection pool.

What are some common pitfalls when using mutexes?

Common pitfalls include deadlocks, priority inversion, and forgetting to release the mutex after acquiring it.
