Different programming languages and platforms may provide different ways to use atomic operations in concurrent programming. Some languages, such as Java, C#, and Go, have built-in support for atomic operations, either as keywords or as library functions. For example, in Java, you can use the keyword synchronized to mark a block of code or a method as atomic, or you can use the classes in the java.util.concurrent.atomic package to perform atomic operations on various types of variables. In C#, you can use the lock statement to create a critical section, or you can use the methods in the System.Threading.Interlocked class to perform atomic operations on integers, references, and other types of variables. In Go, you can use the sync package to create mutexes and atomic variables, or you can use the sync/atomic package to perform atomic operations on integers, pointers, and booleans.
Other languages, such as C and C++, may not have native support for atomic operations, but they may rely on compiler directives, library functions, or hardware instructions to achieve them. For example, in C and C++, you can use the _Atomic keyword or the stdatomic.h header to declare and manipulate atomic variables, or you can use the functions in the atomic.h header to perform atomic operations on memory locations. Alternatively, you can use platform-specific or vendor-specific extensions, such as GCC's __sync or __atomic built-in functions, or Intel's intrinsics for x86 processors.
