How do I use atomic variables in C++11?

What are atomic variables in C++11?

Atomic variables in C++11 are types that provide a way to perform operations on shared data without using locks, ensuring thread safety.

How do I declare an atomic variable?

You can declare an atomic variable using the std::atomic template. For example: std::atomic<int> myVar;.

Can you show me an example of using atomic variables?

Sure! Here's a simple example:

#include <atomic>
#include <iostream>

std::atomic<int> counter(0);

void increment() {
    counter++;
}

int main() {
    increment();
    std::cout << "Counter: " << counter.load() << std::endl;
    return 0;
}

What are the benefits of using atomic variables?

The benefits include avoiding data races, improving performance by reducing the need for locks, and simplifying code for concurrent programming.
