A namespace is a declarative region that provides a scope for its internal identifiers (names of types, functions, and variables). Namespaces are used to organize code into logical groups and can also be used to avoid name collisions, especially if

Defined:Using overlay technology, several variables cover each other so that several different variables share the same memory structure and become the community type structure. The definition of a community is similar to a struct, but all members
