Com: Garbage Collection: Algorithms for Automatic Dynamic Memory Management : Richard Jones, Rafael D Lins: Books. These are not garbage collected - you need to explicitly free every pointer that you allocated. A computer's memory storage and management is also handled by the operating system. As I discussed in my last post on Memory Allocation dynamic memory is hard to manage One of the duty of a GC system is to automate this process by tracking down (using various algorithms) such objects and reclaim the memory used by them automatically. C++ supports dynamic memory allocation with the help of new and delete. IMO this is almost a no-brainer. There is no actual allocation or deallocation going on: the space in the automatic memory (AKA "on the stack") is allocated by some compile-time bookkeeping around the stack pointer. The access of automatic variables is a very fast assisted by hardware, so there is no loss of efficiency there. Garbage Collectionâ€"Part 2: Automatic Memory Management in the Microsoft . Garbage Collection does exactly what it's more fancier name “Automatic dynamic memory management” suggests. Memory Management: Algorithms and Implementation in C/C++ presents several concrete implementation of garbage collection and explicit memory management algorithms. I'll explain what it is, how it (A dynamic array automatically expands when adding new elements, unlike a normal C array.) Here's the . A half way to garbage collection is to use private heaps, that is, you first allocate a big chunk of memory and manage it in a Heap class (whenever you need new memory to be allocated, a request is being made to the Heap class). It doesn't support automatic garbage collection, one of the most important features introduced in Java. One technique which can make memory management a lot easier is reference counting, which this article is about. The Garbage Collection Handbook The Art of Automatic Memory Management - Garbage Collection: Algorithms for Automatic Dynamic Memory Management (운영체제와 컴파일러에 정통하� 분은 금방 보는 참고서일뿐 ㅡ. If even reference counting is too tedious for you, then maybe you want garbage collection, which almost completely eliminates manual memory management — but garbage collection is way outside the scope of this article. Dynamic memory allocation (Java-style) is done with malloc / calloc / realloc in C. SUMMARY The first part of this two-part article explained how the garbage collection algorithm works, how resources can clean up properly when the garbage collector decides to free a resource's memory, and how to force an object to clean up .. Garbage collection deals with the automatic management of dynamic memory. Many modern languages such as C# and Java provide garbage collection, in which the system automatically identifies memory that is no longer accessible by the program and releases it back to the memory manager. This brings me to one of the more controversial features of high level languages: garbage collection.
