Re: Problems with cin.getline on solaris 2.x

[Nathan Neulinger <nneul at umr dot edu>]

It's not me doing it. It's students and faculty. I'm just passing along
a reproducible failure. 

If I change that to #include <iostream>, I have to add 'using namespace
std;', and it makes no difference to the end result. Still fails.

That syntax may be deprecated, but there is still a LOT of code out
there using it, and a lot of books that list it the old way as well. 

Thanks for the attempt though.
