Hey, i just got a book on C++, and i didnt get very far in it. To be truthful, i didnt get too far past the hello world program. I'm having truble comprehending what the line:

useing namespace std;

means.
Everything else is clear. The book says that the line "states that we are using statements of the std family". That would have been a valid explination to me if the hello world program didnt work without it. Can someone enlighten me about this namespace thing? Also, the tutorials here at Cprogramming mention nothing of this(i think).
