Most of the C++ programmers do not benefit from "Garbage Collection" technique (GC). They are sick of deleting objects but have to do this. There are some C/C++ memory GC implementations, but they are complex and are not widely used. I am going to introduce a new memory management technique named "GC Allocator". "GC Allocator" isn't an implementation, but a concept. Now, we have two "GC Allocator" implementations, named "AutoFreeAlloc" and "ScopeAlloc". This article consists of three parts: 1. What is GC Allocator? 2. GC Allocator implementations: ScopeAlloc and AutoFreeAlloc 3. Applications based on GC Allocator For more information, see http://www.codeproject.com/KB/cpp/gc-allocator.aspx To obtain a copy of this paper in pdf format click here<http://xushiwei.com/local--files/gc-allocator/GCAllocator.pdf>(or from google code <http://code.google.com/p/stdext/downloads/list>).
