Title: Exploring the Fundamentals of Pascal Programming: A Comprehensive Overview

Introduction:

Pascal, named after the French mathematician and philosopher Blaise Pascal, is a high-level, procedural programming language designed in the late 1960s and early 1970s by Niklaus Wirth. It was initially intended for educational purposes, emphasizing structured programming and data structuring. Despite its age, Pascal remains relevant due to its simplicity, readability, and strong typing system.
