ya, I had that same issue too... throughout the year I would not use namespace cuz it didn't appear to do anything, but sometimes I would get random errors for no reason and namespace would fix them
so now I use it

ok, honest to God, what the heck is a namespace? i see this just about everywhere i go, right under the includes and i just don't get why it's used. something to do with preventing naming conflicts in C++ apparently. but when would you get a naming conflict? and what would happen if you did get one? is the namespace part of the program always necessary? |

really? i've done it without namespace. in dev-c++ i just you cout without the std:: part in front and it worked fine |

some compilers will do the std namespace for you since its a standard |

I use it, simply because I'm lazy so if I never use std big deal, and if I do then I don't have to worry about it, I just put it up at the top with my #include and #ifndef |

Basically, <i>using namespace std</i> means that all functions under the scope of std don't have to be written like std::foo. It's a bit more complex than that, but basically, all the functions in the Standard Template Library are under the namespace std. So to access them, you go std::cout or whatever. Say you have another namespace, called boo, and it has a function called cout, you'd call it by going boo::cout. Now, when you say <i>using namespace std</i>, you say that when you type cout, it will automatically mean std::cout. Otherwise, the compiler will be like, did you mean the boo namespace, or the std namespace? |
