What is the difference between these two?
I have just begun learning c++ and what i have learned online and what i have learned from a book are two different ways to get the same ending product. What exactly is the difference between the two? Since the output is the same is it just preference?
std::cout <<" Hello World " << std::endl;
and
cout << " Hello World " << endl;
std::cout <<" Hello World " << std::endl;
and
cout << " Hello World " << endl;
its more than preference, std:: is a namespace so that functions and classes with the same name don't conflict, the second method is the worst one.

what he said BUT if your just beginning i would use
using namespace std;
because it is simpler, do this until you learn about namespaces an about using the std::
so the second is simplicity, and the first one is for more specific functions that are used by more experienced people.
