reply thanks. Sort of off topic but does foreach need access to iterator (and not const_iterator).. like i have class B deriving from private std::vector<int> i allow const_iterator but not iterator. I get compile time error.

You mean, you want to get an iterator representing the current position
of the iteration? Sorry, you can't do that. Don't use FOREACH; use a
