How to use std::atomic<>

Question

I have a class that I want to use in different threads and I think I may be able to use std::atomic this way:

class A
{
    int x;

public:
    A()
         


        

Answer 1

Declare the class member x as atomic, then you don't have to declare the object as atomic:

class A
{  
   std::atomic x;
};
