What is the difference between atomic and non-atomic variables?

What is the difference between atomic and non-atomic variables?

Atomic variables are indivisible and thread-safe, while non-atomic variables can be accessed by multiple threads without safety.

Can you give me an example of when to use atomic variables?

Sure! Use atomic variables in multi-threaded applications where you need to ensure that a variable's value is updated safely.

What are the performance implications of using atomic variables?

Atomic variables can be slower than non-atomic ones due to the overhead of ensuring thread safety, but they prevent data races.

Are there any programming languages that don't support atomic variables?

Most modern programming languages, like Java, C++, and Python, support atomic variables, but the implementation may vary.
