Newbie to the course here

I am here as per the instructions of the course. Now, “using namespace” for a small program like Bulls and Cows shouldn’t be a problem. But I do believe that calling out the namespace and then the member is a wiser method. Another advantage I think we could have is when we start using multiple cpp files. Not sure, butt that is my thinking, at the moment.

I learned C++ quite sometime ago but don’t remember getting explanation for libraries. Nada.
