:) Well the using std::thing is elegant when used for only 2-3 names.
Here indeed we could do that since we use only cout, endl, and
getchar().


The using namespace std; is an attempt to defeat the namespace system
when we use it in global scope (as many folks do) and i think everyone
can realise that. Well i am using it in local scope.


So in summary, use using std::thing when there are only 2-4 names and
using namespace std; when there are more. And these, in as small scope
as possible.


So, the using namespace something; and using something::thing are not
prohibited in local scopes. :)
