What are the best practices for thread safety in C++?

What are the best practices for thread safety in C++?

Thread safety in C++ can be achieved through several best practices, such as using mutexes, avoiding shared mutable state, and employing atomic operations.

Can you explain how mutexes work in C++?

Mutexes are synchronization primitives that prevent multiple threads from accessing shared resources simultaneously, ensuring data integrity.

What are atomic operations and when should I use them?

Atomic operations are low-level operations that complete in a single step relative to other threads. They are useful for simple data types where you want to avoid the overhead of mutexes.

Are there any libraries that can help with thread safety?

Yes, libraries like Boost and C++11's standard library provide various tools for managing thread safety, including mutexes, locks, and condition variables.
