std::vector is a template, so you need to specify what type it
contains.  In this case, it's int.  The previous line should therefore
read:

        vector<int>v1(val, val + 10);

As Mr. Broeker suggested, questions like this are probably better
directed to the comp.lang.c++ or comp.lang.c++.moderated newsgroups,
since this type of question isn't djgpp specific.

Best regards,
