hello group,
is it possible to get the size of iterated object:
"sizeof(typenam e iterator_traits <InputIterator> ::value_type);"
and NOT using dereferencing
sizeof(*theIter ator); ?
thanks & hand, chris 2 2383

Yes, but it doesn't matter, since the argument of a sizeof
operator is never evaluated (except by the compiler, to
determine its type).

Looks good to me.
>and NOT using dereferencing sizeof(*theIte rator); ?
IMO nothing wrong with that since the deferencing will never occur but
the iterator_traits <>::value type is fine.
Ah, thanks. Its only because of the dereferencing. I forgot that
sizeof() ist compiler-related...

encapsulates a set of ranges and abstracts out code to handle
traversal through all of them as though all the...

Hi,
Does anyone know a good (c++)example of the implementation of a
"robust" list iterator (ie an iterator whereby insert/delete
operations does not have any effect on the list)?
I am looking for an implementation that does not make copies of the list.
thanks in advance,

Hi.
Let me introduce an iterator to you, the so-called "Abstract Iterator"
I developed the other day.
I actually have no idea if there's another "Abstract Iterator" out
there, as I have never looked for one on the net (I did browse the
boost library though). It doesn't matter right now, anyway.
To put it simply, Abstract Iterator is mainly a wrapper class. It helps

I understand why it is not safe to inherit from STL containers, but I have
found (in SGI STL documentation) that for example bidirectional_iterator

In that book, on pages 68-69, definition has been given that "an

As per this definition, on page 71 in this book, it is mentioned that

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
