## 20.7 Name Spaces - the `using` directive

- Dumps entire namespace (or selected names) into global namespace
- Avoids using fully qualified names
- Beware of conflicts
- To add entire namespace:

  > `using namespace std;`

- To pick which names to add:

  > `using std::cout; // Include only cout from the std namespace`

- Do not put `using` statements in header (included) files
