What are atomic operations and how do they differ in various programming languages?

Atomic operations are indivisible operations that complete in a single step relative to other operations. They ensure data integrity in concurrent programming.

Can you give examples of atomic operations in languages like C++, Java, and Python?

Sure! In C++, you can use std::atomic for atomic operations. In Java, the java.util.concurrent.atomic package provides classes like AtomicInteger. Python has the threading module with Lock for similar functionality.

Are atomic operations always faster than non-atomic ones?

Not necessarily. While atomic operations can prevent race conditions, they may introduce overhead due to locking mechanisms, making them slower in some scenarios.

What are the potential pitfalls of using atomic operations?

Potential pitfalls include deadlocks, increased complexity in code, and performance issues if overused, as they can lead to contention among threads.
