Pascal
In plain terms
A structured teaching language that influenced many later languages.
Going deeper
Pascal was designed for clarity and good programming habits, widely used in education and early software. Its disciplined structure shaped modern language design.
Under the hood
Strong typing and readable structure made it a teaching staple; Object Pascal (Delphi) extended it for real-world apps.
Examples
Computer science education, early Mac/PC software, Turbo Pascal, Delphi.
