What are the best practices for concurrency in C++14?

In C++14, some best practices for concurrency include using std::thread for creating threads, std::mutex for protecting shared data, and std::lock_guard for automatic locking.

Can you explain how std::lock_guard works?

Sure! std::lock_guard is a RAII-style wrapper that locks a mutex when created and automatically unlocks it when it goes out of scope, ensuring that the mutex is always released.

What about using futures and promises?

Futures and promises in C++14 allow you to write asynchronous code. A promise is used to set a value that a future can retrieve later, enabling synchronization between threads.

Are there any common pitfalls to avoid?

Yes, common pitfalls include deadlocks, race conditions, and not properly managing the lifetime of shared resources. Always ensure proper synchronization.
