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 that guarantees safe execution by multiple threads. It's important to prevent data races and ensure that shared data is accessed in a controlled manner.

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

You can achieve thread safety in C++ using various techniques such as mutexes, locks, and atomic operations. Mutexes prevent multiple threads from accessing shared resources simultaneously.

What are some common pitfalls when dealing with thread safety?

Common pitfalls include deadlocks, race conditions, and improper use of locks. It's crucial to design your threading model carefully to avoid these issues.

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

Yes, C++11 introduced the <thread> library, which provides tools for managing threads, along with <mutex> for synchronization and <atomic> for atomic operations.
