How Does the std::atomic Library Facilitate Concurrent Programming in C++?

The std::atomic library helps C++ developers manage concurrency safely and efficiently.

It provides a way to perform atomic operations, ensuring that operations on shared data are thread-safe without needing a lock. For example:

#include 
std::atomic counter(0);
counter.fetch_add(1);

Atomic operations are essential in multithreaded environments because they prevent race conditions. Unlike traditional mutexes, they don’t require locking, leading to higher performance in certain situations.

Understanding and using std::atomic is crucial for developing lock-free and scalable applications.
