How does C++ handle thread synchronization?

How does C++ handle thread synchronization?

C++ provides several mechanisms for thread synchronization, primarily through the Standard Library's <thread> and <mutex> headers.

Can you explain how mutexes work in C++?

Mutexes, or mutual exclusions, are used to protect shared data from being accessed by multiple threads simultaneously. You lock a mutex before accessing shared data and unlock it afterward.

What are some common pitfalls when using mutexes?

Common pitfalls include forgetting to unlock a mutex, leading to deadlocks, and using a mutex in a way that can cause performance bottlenecks.

Are there alternatives to mutexes for synchronization?

Yes, alternatives include condition variables, atomic operations, and read-write locks, each suited for different scenarios.
