> You can do this quite well using the standard library and stream iterator > adapters. This may do both of your approaches above. For example: [...] > typedef std::ostream_iterator<std::string> Out; > > std::cout << "Print vector\n"; > std::copy(list.begin(),list.end(),Out(std::cout,"\n")); Now try the same with std::map< std::string, std::vector< std::vector<int > > >. With op<<, it's still one statement. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
