Garbage Collection in C++ — why?

Question

I keep hearing people complaining that C++ doesn\'t have garbage collection. I also hear that the C++ Standards Committee is looking at adding it to the language. I\'m afrai

Answer 1

With the advent of good memory checkers like valgrind, I don't see much use to garbage collection as a safety net "in case" we forgot to deallocate something - especially since it doesn't help much in managing the more generic case of resources other than memory (although these are much less common). Besides, explicitly allocating and deallocating memory (even with smart pointers) is fairly rare in the code I've seen, since containers are a much simpler and better way usually.

But garbage collection can offer performance benefits potentially, especially if alot of short lived objects are being heap allocated. GC also potentially offers better locality of reference for newly created objects (comparable to objects on the stack).
