When you use "using namespace (INSERT NAMESPACE HERE);" all symbols(functions and stuff) in that namespace will become visible/available without adding the namespace prefix. For example, if you were to use cout w/o delcaring "using namespace std", you would need to use "std::cout" instead of "cout".

Basically its to make life easier w/o having to use "std:: ..." all the time when you are calling something from the std library. if you want more detailed information, google it.
