What are the benefits of using atomic operations in C?

Atomic operations in C provide a way to perform operations on shared data without the need for locks, ensuring data integrity.

Can you explain how atomic operations improve performance?

Sure! They reduce the overhead of locking mechanisms, allowing multiple threads to operate on shared data more efficiently.

Are there any downsides to using atomic operations?

Yes, while they are faster, atomic operations can lead to subtle bugs if not used carefully, especially in complex scenarios.

What types of atomic operations are available in C?

C provides several atomic operations like atomic increment, decrement, and compare-and-swap, typically through the stdatomic.h header.

How do I implement atomic operations in my C code?

You can use the functions defined in stdatomic.h, such as atomic_fetch_add or atomic_compare_exchange_strong, to implement them.
