using namespace std;

are you able to overwrite it for a specific line e.g ios::app while using the fstream header? or does that mean i have to use std:: on everything else?

Without the using namespace std; you will have to preface most everything from the libraries with std:: (and who wants lots of std's in this day and age?;)

Without it, you might have to open a file like

std::fstream fin ("text.txt", std::ios::in );

The using statement makes everything in the libraries directly available to you , saving a lot of writing.

I understand that lol. Im sorry, i guess my question, is ios:: included in the std namespace? Thanks =)
