  • 01:1301:13, 9 August 2019 diff hist +449 Associative arrayUndid revision 909984157 by 185.213.154.172 (talk) Clarified the missing association between Unique Strings, Unique keys, and Key-value tuples from my Discrete Structures CS 250 textbook. The article as previously was written had some huge holes in it big enough to fit a ship through. You can't just put up a definition in Wikipedia that is wrong on its face. C++ std lib calls it a map<Char,T>, not just a map. Tag: Visual edit

  • 20:3920:39, 8 August 2019 diff hist +170 Associative arrayUndid revision 909964057 by 185.213.154.172 (talk) The heading does summarize the body of research, a mapping is a "binding" but binding is not set theory langua. A collection is not an Abstract data type, nor is it a part of set theory, and thus can't be used to define an ADT required to be defined by set theory. Not all shapes are circles, likewise not all maps are dictionaries. C++ doesn't define what a map means. Tag: Undo
  • 18:3218:32, 8 August 2019 diff hist +17 Associative arrayA string may be mapped to the empty set. The null object is not the empty set because it has an address of 0 while the empty set has no address. The null object is an abstraction that is not required for an assocaitive array as an Abstract data type. Tag: Visual edit
  • 18:1118:11, 8 August 2019 diff hist +142 Associative arrayUndid revision 909947277 by Macrakis (talk) Definition must be defined by set theory. An Associative array is a TYPE of map but not all maps are Associative arrays. A function has to have an input in the domain and an output int he range with mappings from the codomain into the domain, & the empty set is member of both. The member of the codomain may be a member of another set called Values, but that is a defined by the map definition. Tag: Undo
  • 16:3516:35, 8 August 2019 diff hist +143 Associative arrayAn Abstract Data Type is defined very specifically as being defined by set theory and thus is required to be defined by set theory in wiki, and it's a Surjective map to be exact. A collection of key-value tuples may contain a duplicate key and thus is an Associative LIST and not an Assocaitaive ARRAY (Wiki List computer science). A map is not an Associative array, it's a MAP that may not be onto. The C++ people had some grandiose cooky reason for calling it map due to passing int as a string. Tag: Visual edit

  • 15:2915:29, 28 July 2019 diff hist +74 Associative arrayThe C++ folks named their associative array Map because they abstracted away the hash table so it's not actually an associative array because it does more than just strings. An Associative array is defined as the mathematical definition of a map of unique strings to an instance of an object. Tag: Visual edit
