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.
