What are concurrency models in C++?

What are concurrency models in C++?

Concurrency models in C++ refer to the ways in which multiple threads can operate simultaneously, allowing for efficient execution of programs.

Can you explain the different types of synchronization mechanisms?

Sure! Common synchronization mechanisms include mutexes, semaphores, condition variables, and barriers, each serving different purposes.

How do mutexes work in C++?

Mutexes, or mutual exclusions, are used to protect shared resources by allowing only one thread to access the resource at a time.

What are the advantages of using condition variables?

Condition variables allow threads to wait for certain conditions to be met before proceeding, which helps in efficient resource management.

Can you give an example of using a semaphore?

Certainly! A semaphore can be used to control access to a pool of resources, like limiting the number of threads accessing a database.
