Stephan,

Great series.  These lectures are not only informative but the energy you show really has me delving into the STL.  Being as though this is very new to me I have a request.  In your example above (part of homework part 2) could you add/supply an example of how to use the erase_if for an associative container (preferably map).  Having difficulty getting the predicate correct.

Thanks,

Mike
