Can you explain the differences between semaphores and mutexes?
Sure! Both semaphores and mutexes are synchronization primitives used in concurrent programming, but they serve different purposes.
What is the main purpose of a mutex?
A mutex, or mutual exclusion, is used to ensure that only one thread can access a resource at a time, preventing race conditions.
And what about semaphores?
Semaphores can allow multiple threads to access a limited number of resources. They maintain a count to control access.
Can you give an example of when to use each?
Use a mutex when you need exclusive access to a resource, and use a semaphore when you want to limit access to a pool of resources.
