=====using=====
The using keyword is used to import a namespace (or parts of a namespace) into
the current scope.
Example code:
For example, the following code imports the entire std namespace into the
current scope so that items within that namespace can be used without a
preceeding "std::".

<code>
   using namespace std;
</code>
Alternatively, the next code snippet just imports a single element of the std
namespace into the current namespace:

<code>
   using std::cout;
</code>
