It is very funny that you write that. D1 is a stable language and there is a
lot of code written using it.
There is absolutely nothing that can be written in C++ and can't be in D
(unless you are writing for a memory-limited embedded device).
In fact, D is a lot more powerful than C++ already, and it allows to you
complete the same task faster and with less code.

 2.Are those feathers in D2 vital  while D1 does not have?Or all these

I believe there is little difference between programming in D1 or D2 for a
novice, but I'd recommend sticking with D1 for now because it is more stable,
has a lot more code pre-written for you, common problems are solved, more
experts available etc.
 
 I am lost although I like D so much than C++.I would like to spend as  
 much time as learning C++ and want to gain as much as gain C++ can offer  
 me. Any constructive suggestions or guideline would be much appreicated.

I'd suggest you to write more code, experience and knowledge comes with
practice. Pick a project and start writing code. Whenever you find a
difficulty, ask in newsgroups or in IRC (you usually get instant help there).
I'd also recommend you to find some people that use/learn D and speak your
language. For example, if you speak Chinese, d-programming-language-china.org
is a great resource for you. I believe there are a lot of people that would be
glad to help.

There is also russian community located at dprogramming.ru

Hi Denis,

Thanks so much for your prompt response.

I do know many projects there written by D1,but how come D1 seems to ppl  just
a  pass-by,please correct me if I am wrong.

 Yes,you are right, I am a member of d-programming-language-china.org.Actually
there is another one D forum which I think is more open,serious,intuitive and
productive:
http://dlang.group.javaeye.com/
and I has tried to translate several Phobos lib into Chinese just as the others
did.
But to be honest,almost all D members in the forum are a bit  lost for the
going of D1 vs D2.We felt that D1 is workable but less less power than D2 or
C++( almost not worth to use),D2 is what we expected and what we want but it
seems we can never get it to work.

Thanks again.
Sam

Then more of you should speak up in the newsgroups.  Walter doesn't
speak Chinese.

Where do you get that impression?  Most code that has been written in
D has been written in D1.  Most D libraries are D1-only or at least
D1-compatible.  There is a very small number of D2 projects, and given
how much D2 and Phobos 2 are changing, I doubt that they're terribly
stable.

If you get the impression that since most of the discussions are about
D2 then D1 is dead, well, no.  It's just that D1 doesn't (and can't)
change anymore, so there's no point discussing it.

D1 is very useful and mature imho, you can do anything with it that it was 
designed for and them some more. 

The choice of D1 or D2 is not too difficult: D2 itself is still changing, 
compiler may have more bugs, and there are very, very few libraries for it. 
Even the dsss build tool does not work with latest versions of dmd2. This 
means: only usable for learning, building libraries and generally if you 
want to stay on top of the bleeding edge. Not so suitable for making 
applications yet.

 2.Are those feathers in D2 vital  while D1 does not have?Or all these 

features are just for experienced programmers,a beginner can just ignore 
them at present?

Both are true I think. They really are important improvements, but not in a  
way that makes D1 incomplete without them.

time as learning C++ and want to gain as much as gain C++ can offer me.Any

Is your goal for now *just* to learn D? Then you could start making toy 
programs with D2. Is your goal to learn D and make some cool programs? Then 
D1 will make that easier. 

Happy programming!
