Re: Is bitset class is not a STL container?

Unlike the similar vector<bool> Class, the bitset class does not have
iterators and is not an Standard Template Library container.
Actaully what's so special in STL containers?
What I know is that there will be certain operators overloaded,
supports template meta programming, having iterators, compatible with
other STL functions etc...
It would be helpful if you says what's missing in bitset container.
First of all I think the term STL is a bit old, once there was
something called STL but that was later included in what is now know
as the C++ standard library. And bitset is part of the standard
library (I don't know if it was part of the original STL).
I think what you are asking about is what the difference between
bitset and the other containers in the standard library is, and I'd
answer that most of the normal container are generic and dynamic.
Meaning that they can contain elements of any type and are not fixed
in size.
The bitset on the other hand only contains bits (bools) and have a
fixed size. It's a very specialized container that can (which the
normal containers can't) perform some operations on all elements at
once (flip() is an example).
Since bitset is so specialized it does not make much sense to provide
some of the features that normal containers have (iterators is one
such feature) since in many cases there would be no use for the
features that would make sense.
