No.

It is a major difference between C++ and languages
like Java and C#.

No.

C++ use RAII.

In theory you can add GC to C++ and a few academic reserach
projects has done so.

I have never heard about a C++ project actually using it.

And it is not a standard C++ feature.

Maybe you should read it.

If it is the same as in the special edition then it is a half page.

And it is very clear: "The standard does not require that an 
implementation supply a garbage collector".

And Bjarne does not want it added to the language. See:
