What are some examples of atomic operations in C++?

What are some examples of atomic operations in C++?

Atomic operations in C++ are operations that complete in a single step relative to other threads. Examples include atomic increment, decrement, and compare-and-swap.

Can you explain how atomic increment works?

Sure! Atomic increment increases the value of a variable by one in a thread-safe manner, ensuring no other thread can modify it during the operation.

What header file do I need to include for atomic operations?

You need to include the <atomic> header file to use atomic operations in C++.

Are there any performance considerations with atomic operations?

Yes, while atomic operations are thread-safe, they can be slower than non-atomic operations due to the overhead of ensuring thread safety.
