Can you give me some examples of atomic operations in C++?
Sure! In C++, atomic operations can be performed using the <atomic>
header. For example, you can use std::atomic<int>
to create an atomic integer.
How do I increment an atomic integer safely?
You can use the fetch_add
method. For instance: atomicInt.fetch_add(1);
This increments the value atomically.
What about atomic booleans? Can you show me an example?
Absolutely! You can use std::atomic<bool>
. For example: std::atomic<bool> flag(false); flag.store(true);
sets the flag atomically.
Are there any performance considerations I should be aware of?
Yes, atomic operations can be slower than non-atomic ones due to memory synchronization. Use them judiciously.
