What is thread safety in C++ and why is it important?

Thread safety in C++ refers to the property of a program or code segment to function correctly during simultaneous execution by multiple threads. It's important because it prevents data races and ensures that shared data is accessed in a controlled manner.

Can you explain how to achieve thread safety in C++?

To achieve thread safety in C++, you can use synchronization mechanisms like mutexes, locks, and condition variables. These tools help manage access to shared resources.

What are some common pitfalls when dealing with thread safety?

Common pitfalls include deadlocks, race conditions, and improper use of synchronization primitives. It's crucial to design your code carefully to avoid these issues.

Are there any libraries in C++ that help with thread safety?

Yes, the C++ Standard Library provides several features for thread safety, such as the <thread> library for managing threads and <mutex> for synchronization.
