Description #

Pascal is a structured, statically typed programming language designed for teaching programming concepts and developing reliable, maintainable software. It emphasizes clear syntax and strong data typing.

History #

Pascal was created in 1970 by Swiss computer scientist Niklaus Wirth. It was developed as a teaching tool to encourage good programming practices using structured programming and data structuring. During the 1980s and early 1990s, Pascal was widely used in academia and commercial applications. Variants like Turbo Pascal and Object Pascal (which evolved into Delphi) extended Pascal’s influence in real-world software development.
