What are stdatomic and memory models in C++?

Can you explain what stdatomic is in C++?

Sure! stdatomic is a header in C++ that provides atomic operations for variables, ensuring safe access in concurrent programming.

How does stdatomic relate to memory models?

stdatomic is closely tied to memory models as it defines how operations on atomic types interact with memory, ensuring consistency.

What are the key memory models in C++?

The key memory models in C++ include sequential consistency, relaxed consistency, and acquire-release semantics, each defining different guarantees.

Can you give an example of using stdatomic in code?

Certainly! Here's a simple example: std::atomic<int> counter(0); allows safe incrementing of counter in a multi-threaded environment.
