What are the key features of C++17 for parallel programming?

C++17 introduced several features that enhance parallel programming, including parallel algorithms, std::optional, and std::variant.

Can you explain how parallel algorithms work in C++17?

Parallel algorithms in C++17 allow you to execute operations on containers in parallel, improving performance. You can use the execution policies like std::execution::par.

What are execution policies and how do I use them?

Execution policies define how algorithms are executed. You can specify sequential or parallel execution using std::execution::seq or std::execution::par.

Are there any limitations or considerations when using parallel algorithms?

Yes, you need to ensure that your operations are thread-safe and that the data structures you use are suitable for concurrent access.
