Example of program organization
The standard library namespace
Point Exercise - C++ versus C#
The standard library namespace
All facilities in the C++ Standard Library are defined in the
std
namespace
Namespace resolution
Use the scope operator
::
on every name you use from the standard name space
std::cout << s1 << std::endl;
Allows for symmetric use of the same names from other namespaces
Tedious in short and simple programs
Apply using declarations on selected names from the standard namespace
using std::cout; using std::endl;
Tedious, just in another way...
Apply a single using directive
using namespace std;
All names from the standard namespace can be used without qualifiction
OK for namespace composition - OK in certain local scopes
Sloppy and lazy
if used in the global namespace
