What is a namespace? What happens when two namespaces having the same name?
- A conceptual space for grouping identifiers, classes etc. for the purpose of avoiding conflicts with the elements of an unrelated code which have the same names.
- When two name spaces are having same name, the corresponding compiler uses our name spaces instead of the type.
Define namespace in C++.
Namespaces groups together entities like classes, objects and functions under a name. Namespaces provide a way to avoid name collisions of variables, types, classes or functions. Namespaces reduces the use of nested class thus reduces the inconvenience of handling nested class.
Define namespaces.
- Namespace is used to group together all the related classes.
- To use namespace, using keyword or scope resolution operator can be used.
namespace emp
{
class Manager
{
public:
static void showDetail()
{
....
...
}
};
}
- To use :
emp::Manage::showDetail();
or
using namespace emp;
Manager::showDetail();
