What are some use cases for atomic operations in C++?
Atomic operations in C++ are used in multithreading to ensure data integrity without locks. Common use cases include counters, flags, and shared resources.
Can you explain how atomic operations improve performance?
They reduce the overhead of locking mechanisms, allowing threads to operate on shared data more efficiently, which enhances performance.
What are some examples of atomic operations in C++?
Examples include atomic increment, compare-and-swap, and atomic flags, which are provided in the <atomic> header.
Are there any drawbacks to using atomic operations?
Yes, while they are faster than locks, they can lead to subtle bugs if not used carefully, such as race conditions.
