Nim is usually garbage-collected or reference-counted by default, depending on its configuration, but the programmer may use the switch --mm:none to deallocate memory manually. [ 21 ] Objective-C and Objective-C++ support optional reference counting and garbage collection as alternatives to manual memory management (Apple deprecated the garbage ...

All non- Java virtual machine (JVM) languages, such as Go , JavaScript , C , C++ or assembly , need the help of JVM language code, that may be supplied by ...
As an example use case of compare-and-swap, here is an algorithm for atomically incrementing or decrementing an integer. This is useful in a variety of applications that use counters. The function add performs the action *p ← *p + a, atomically (again denoting pointer indirection by *, as in C) and returns the final value stored in the counter.
