What are the best practices for threading in modern C++?

In modern C++, it's essential to use the standard library's threading features, like std::thread, std::mutex, and std::lock_guard. Always prefer RAII for resource management.

Can you explain RAII and why it's important for threading?

RAII stands for Resource Acquisition Is Initialization. It ensures that resources are properly released when they go out of scope, which is crucial in multithreaded environments to prevent deadlocks.

What are some common pitfalls to avoid when using threads?

Common pitfalls include data races, deadlocks, and not properly managing thread lifetimes. Always ensure shared data is protected with mutexes.

How can I safely share data between threads?

You can use mutexes to protect shared data, or consider using higher-level abstractions like std::atomic or concurrent data structures from the C++ standard library.
