What are atomic operations in C++ threading?

What are atomic operations in C++ threading?

Atomic operations are low-level operations that complete in a single step relative to other threads, ensuring data integrity.

Can you give me an example of an atomic operation in C++?

Sure! An example is using std::atomic<int> to safely increment a counter across multiple threads.

How do atomic operations improve performance in multithreading?

They reduce the need for locks, which can be expensive, allowing threads to operate more efficiently.

Are there any drawbacks to using atomic operations?

Yes, while they are faster than locks, they can lead to complex code and may not be suitable for all scenarios.
