Container requirements

[subramanian100in]

In the ISO/IEC 14882-2003 document, in page 468 in section 23.1
'Container requirements', in item 10, the following line is mentioned:

- no copy constructor or assignment operator of a returned iterator
throws an exception.

I am unable to understand what is the 'returned iterator'. Kindly
explain this line with example.

Thanks
V.Subramanian

If you call something like container.begin() or container.end(), it
returns an iterator. You can assign or copy that iterator with an
assurance that doing so will never throw.
