Ah I tend to not use [] operators on vectors etc. but as you say iterators can be problematic. The best way is to start at the end of the container and work backwards, particularly if you are removing items from the list (thereby wrecking the iterator's idea of the end position if you were moving forwards through it).

I should probably finish Bjarne's C++11 book - I am maintaining a codebase of old style C++ and seem to be stuck in the old methods of doing it, mainly because of using compilers that don't have C++11 support.

Is there any recommended reading on new style C++ other than Bjarne's book?
