What are the key threading features introduced in C++11?

C++11 introduced several key threading features, including std::thread, mutexes, and condition variables. These allow for easier and safer multithreading.

Can you explain how std::thread works?

Sure! std::thread allows you to create a new thread of execution. You can pass a function or a callable object to it, and it will run that in a separate thread.

What are mutexes and why are they important?

Mutexes are used to protect shared data from being accessed by multiple threads simultaneously, preventing data races and ensuring thread safety.

How do condition variables work in C++11?

Condition variables are used for thread synchronization. They allow threads to wait for certain conditions to be met before continuing execution.

Are there any performance considerations when using these features?

Yes, while threading can improve performance, improper use can lead to overhead from context switching and potential deadlocks.
