How do I use atomic operations in C++?

You can use the <atomic> header in C++ to perform atomic operations. What specific operation are you interested in?

I want to know how to use atomic variables.

You can declare an atomic variable using std::atomic<Type>. For example, std::atomic<int> counter; allows you to perform atomic operations on an integer.

Can you show me an example of incrementing an atomic variable?

Sure! You can use counter.fetch_add(1) to increment the atomic variable safely. This ensures that the operation is thread-safe.

What happens if I don't use atomic operations?

Without atomic operations, you may encounter data races, leading to undefined behavior when multiple threads access shared data.
