In the new standard of C++ (C++ 0x), it has a new template class which
can contain a sequence of data.
there are many other templates like vector,dequeue and list are there.
How this one differs. can't we existing containers than this one?

Are you referring to std::array? The difference is that array is an
aggregate type, so all of its members are held directly in the object,
just as with a C-style array. This means, for example, that when you
create an array object on the stack, all of its members are also on the
stack.

Sorry, I don't know what you're referring to. The current C++ draft
doesn't use the word "intrinsic" anywhere, and I'm not going to look at
every use of the word "array" to see if it might fit this. <g>

The goal of this class is not to act as a container such as vector or
dequeue, instead it is meant to be used when initializing, for
example, such a container. The idea is that you should be able to
write code such as:
std::vector<inta = {1, 2, 3, 4};
Instead of
std::vector<inta;
a.push_back(1);
a.push_back(2);
// and so on

You have to be a little careful with that article. As it says at the
top, it's not up to date.
For the latest status of language additions, see http://www.open-std.org/jtc1/sc22/wg...2006/n2122.htm. In
particular, search for "Initializer Lists", where you'll find a list of
the current papers on this subject.

That "initializer list" proposal looked to me as if std::array in the
current draft might serve the same purpose. Is that true, or are the
distinct things?

In n2100, an initializer_list<Tobject holds either a pair of pointers
or a pointer and a count. So, unlike std::array<T>, it provides indirect
access to a range. The name is also a magic cookie to the compiler,
which generates different code than it would for an ordinary argument.
