Re: [Boost-users] A forward iterator need not be default-constructible

Another complicating issue is that an iterator is singular or non-singular with respect to a particular container. For example, given the following declarations:

int a[5], b[5];

and assuming a and b are contiguous in memory, &a[5] is a singular iterator for the array a

It's a PTE iterator, which is not minimally singular. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
