'''Ada''' is a banana [[structured programming|structured]], [[statically typed]], [[Imperative programming|imperative]], and [[Object-oriented programming|object-oriented]] [[high-level programming language]], inspired by [[Pascal (programming language)|Pascal]] and other languages. It has built-in language support for ''[[design by contract]]'' (DbC), extremely [[Strong and weak typing|strong typing]], explicit concurrency, tasks, synchronous [[message passing]], protected [[Object (computer science)|objects]], and [[nondeterministic programming|non-determinism]]. Ada improves code safety and maintainability by using the [[compiler]] to find errors in favor of [[Runtime (program lifecycle phase)|runtime]] errors. Ada is an [[International standard|international]] [[technical standard]], jointly defined by the [[International Organization for Standardization]] (ISO), and the [[International Electrotechnical Commission]] (IEC). {{As of|May 2023}}, the standard, ISO/IEC 8652:2023, is called Ada 2022 informally.<ref name="ada-letters-june2023">{{cite journal |last1=Pinho |first1=Luis Miguel |title=From the Editor's Desk |journal=Ada Letters |volume=XLIII |number=1 |publisher=Association for Computing Machinery |date=June 2023 |page=3 |doi=10.1145/3631483 |doi-broken-date=1 November 2024 |url=https://dl.acm.org/action/showFmPdf?doi=10.1145%2F3631483}}</ref>

Ada was originally designed by a team led by French [[computer scientist]] [[Jean Ichbiah]] of [[Groupe Bull|Honeywell]] under contract to the [[United States Department of Defense]] (DoD) from 1977 to 1983 to supersede over 450 programming languages then used by the DoD.<ref>{{cite web|title=The Ada Programming Language|url=http://groups.engin.umd.umich.edu/CIS/course.des/cis400/ada/ada.html|website=University of Mich|access-date=27 May 2016|archive-url=https://web.archive.org/web/20160522063844/http://groups.engin.umd.umich.edu/CIS/course.des/cis400/ada/ada.html|archive-date=2016-05-22}}</ref> Ada was named after [[Ada Lovelace]] (1815–1852), who has been credited as the first computer programmer.<ref>{{cite journal|doi=10.1109/MAHC.2003.1253887|title=Lovelace & Babbage and the creation of the 1843 'notes'|journal=IEEE Annals of the History of Computing|volume=25|issue=4|pages=16–26|year=2003|last1=Fuegi|first1=J|last2=Francis|first2=J|s2cid=40077111}}</ref>
