The use of namespace is to avoid clash during naming of
variable,classes etc.
Suppose a company wants to release its version of a
function, it can create a separate namespace and then create a
function within that namespace.Another company can create a
function of same name, as long as it is in different
namespace.And the third company can use both the functions
in the same program by using resolving the namespace.
pakage concept of Java is a similar idea.

Namespace is a new concept introduced by the ANSI C++
standards committee. This defines a scops for the
identifiers that are used in a program. For using the
identifiers defined in the namespace scope we must include
the using directive,like
using namespace std;
Here , std is the namespace where ANSI C++ standard class
libraries are defined. All ANSI C++ programs must include
this directive. This will bring all the identifiers defined
in std to the current global scope. using and namespace are
the new keywords of C++.

Answer / achal ubbott
Template feature came to c++ quite later from its birth. It
basically helps some big coders.
Now if u buy 2 libraries from market and both of these
define a class Ethernet; Then if u use both of them in your
code the copiler will give some redeclaration of class
errors. So this Namespace feature helps the coder to
differentiate among the two.
