How does threading in C++17 differ from C++11?

How does threading in C++17 differ from C++11?

C++17 introduced several enhancements to threading, including the addition of std::optional and std::variant, which improve thread safety and data handling.

Can you explain how std::optional helps with threading?

Sure! std::optional allows you to represent optional values without using pointers, making it easier to manage shared data across threads.

What about the changes in the memory model?

C++17 refined the memory model, providing better guarantees for atomic operations and memory ordering, which enhances thread synchronization.

Are there any new synchronization primitives in C++17?

Yes, C++17 introduced std::shared_mutex, which allows multiple readers or one writer, improving performance in read-heavy scenarios.
