Pascal is a higher-level, problem-oriented programming language named after the French mathematician Blaise Pascal (1623-1662), based on Algol 60 and developed by the Swiss Niklaus Wirth. In addition, Pascal is the unit for sound pressure.
Pascal was introduced in 1968 as a teaching language for technical-scientific use, but is used in practice in the commercial, administrative and private sectors. The problem-oriented programming language was standardized in a minimal agreement by the International Standards Organization( ISO).
Pascal is a very clear, hierarchically structured programming language that supports structured programming. The best-known Pascal dialect is Turbo Pascal, developed by the Borland company, from which the object-oriented variant Object P ascal later emerged. In turn, the visual software development environmentDelphi is based on Object Pascal.
