Testing whether an iterator points to the last item?

Question

I have an stl iterator resulting from a std::find() and wish to test whether it is the last element. One way to write this is as follows:

mine *match = some         


        

Answer 1

If you do:

if(itr != Mine.end() && itr == --Mine.end())

It should be fine. Because if itr is not at the end then there must be at least 1 element in the container and so end must yield a value result when decremented.

But if you still don't like that, there are lots of ways to do something equivalent, as all the other answers show.

Here's another alternative:

if(itr != Mine.end() && std::distance(Mine.begin(), itr) == Mine.size()-1)
