What are std::atomic types in C++?

What are std::atomic types in C++?

std::atomic types in C++ are used to provide thread-safe operations on shared data without using mutexes.

Can you give me an example of how to use std::atomic?

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 std::atomic over mutex?

The benefits include reduced overhead, better performance in high contention scenarios, and simpler code for atomic operations.

Are there any limitations to std::atomic types?

Yes, std::atomic types can only be used with certain data types, and they may not support complex operations like compound statements.
