hi,
Try something like this, just add some pointers;
scan is just a simple object and l is a class vector.

This is something like I meant when I said do it the C++ way, or the C
way. Except that I gave a bad example of the C way, this is a better
example, which is of a C++ way. It would help if I knew the C++
iostream stuff better. If this weren't so darned OT, I'd ask what a
"scan" is.
(And is also an example of something that is wrong with the C++ standard
library, when you need the c_str() member of string so often to get any
real useful work done. Kind of defeats the purpose of having string in
the first place.)
The totally unhelpful, but trying to be encouraging,
