Ada is a structured, statically typed, imperative, wide-spectrum, and object-oriented high-level computer programming language, extended from Pascal and other languages. It has built-in language support for explicit concurrency, offering tasks, synchronous message passing, protected objects, and non-determinism. Ada is an international standard; the current version (known as Ada 2012) is defined by ISO/IEC 8652:2012. Ada was originally designed by a team led by Jean Ichbiah of CII Honeywell Bull under contract to the United States Department of Defense (DoD) from 1977 to 1983 to supersede the hundreds of programming languages then used by the DoD. Ada was named after Ada Lovelace (1815–1852), who is credited as being the first computer programmer. (Source:
