What are atomic variables in C?

Can you explain what atomic variables are in C?

Sure! Atomic variables in C are types of variables that are accessed and modified atomically, meaning they are indivisible and prevent race conditions in multi-threaded environments.

Why are atomic variables important in multi-threading?

They are crucial because they ensure that operations on the variable are completed without interruption, which helps maintain data integrity when multiple threads are accessing the same variable.

Can you give me an example of how to declare an atomic variable in C?

Certainly! You can declare an atomic variable using the atomic keyword. For example: atomic int count;.

How do I increment an atomic variable safely?

You can use the atomic_fetch_add function to safely increment an atomic variable. For example: atomic_fetch_add(&count, 1);.
