std::for_each(boost::make_zip_iterator(boost::make_tuple(beg1, beg2, beg3)),
      boost::make_zip_iterator(boost::make_tuple(end1, end2, end3)),
   
);

now i want acess each indivdual tuple values using lambda and bind. How would i do that?

My basic question is how would I use lambda to access the tuples value or each iteration value....
