What is namespace? C++
✍: Guest
Namespaces allow us to group a set of global classes, objects and/or functions under a name. To say
it somehow, they serve to split the global scope in sub-scopes known
as namespaces.
The form to use namespaces is:
namespace identifier { namespace-body }
Where identifier is any valid identifier and namespace-body is the set of classes, objects and
functions that are included within the namespace. For example:
namespace general { int a, b; } In this case, a and b are normal variables integrated within the
general namespace. In order to access to these variables from outside the namespace we have to
use the scope operator ::. For example, to access the previous variables we would have to put:
general::a general::b
The functionality of namespaces is specially useful in case that there is a possibility that a global
object or function can have the same name than another one, causing a redefinition error.
