Basic programming language software software#
Today, Ada is still used for developing very large and critical software systems. At the time of its development, from 1977 – 1983, the Department of Defense was using hundreds of programming languages and Ada was meant to replace all of them. The structured, statically typed, imperative, and object-oriented high-level programming language, is partially based on Pascal and other earlier languages. PTC ApexAda and PTC ObjectAda, DDC-I ScoreĪda was developed in the early 1980s by Jean Ichbiah and his team at CII-Honeywell-Bull in France under contract to the United States Department of Defense. Major Implementations: AdaCore GNAT, Green Hills Software Optimizing Ada 95 compiler, PTC, Inc. [ Developer: United States Department of Defense In 2020 Chinese state media reported that MATLAB had withdrawn services from two Chinese universities as a result of current U.S. MATLAB was a success and has been in continuous use around the world for the last several decades. MATLAB, which began as a simple interactive matrix calculator, allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages.Ĭleve Moler designed MATLAB because he wanted to give his students access to LINPACK and EISPACK (both mathematical software libraries) without them having to learn Fortran. Major Implementations: Used in engineering, science, and economicsĪs its name suggests, MATLAB, developed by MathWorks in the early 1980s, is intended primarily for numerical computing and used by millions of people with backgrounds in engineering, science, and economics.
