In computing, associative containers refer to a group of class templates in the standard library of the C++ programming language that implement ordered associative arrays. Being templates, they can be used to store arbitrary elements, such as integers or custom classes. The following containers are defined in the current revision of the C++ standard: set
, map
, multiset
, multimap
. Each of these containers differ only on constraints placed on their elements.
The associative containers are similar to the unordered associative containers in C++ standard library, the only difference is that the unordered associative containers, as their name implies, do not order their elements.
map
and set
each key must be unique. multimap
and multiset
do not have this restriction.map
and multimap
each element is composed from a key and a mapped value. In set
and multiset
each element is key; there are no mapped values.A map is a symbolic depiction highlighting relationships between elements of some space, such as objects, regions, and themes.
Many maps are static two-dimensional, geometrically accurate (or approximately accurate) representations of three-dimensional space, while others are dynamic or interactive, even three-dimensional. Although most commonly used to depict geography, maps may represent any space, real or imagined, without regard to context or scale; e.g. brain mapping, DNA mapping and extraterrestrial mapping.
Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the medieval Latin Mappa mundi, wherein mappa meant napkin or cloth and mundi the world. Thus, "map" became the shortened term referring to a two-dimensional representation of the surface of the world.
Cartography or map-making is the study and practice of crafting representations of the Earth upon a flat surface (see History of cartography), and one who makes maps is called a cartographer.
Maap (Yapese: Maap′) is an island and village and municipality in the state of Yap, Federated States of Micronesia. It lies on the north east of the archipelago of Yap.
