The first structured programming language was

The name Pascal comes in commemoration of the famous French philosopher and mathematician Blaise Pascal in the seventeenth century. It was designed and founded by Swiss Professor Niklaus Wirth in the late 1960s.

Pascal language has rigorous syntax, clear layers, easy to write programs and strong readability. It is the first structured programming language. Pascal language is widely used in various software. The program is divided into name (self-made after program), setting (specified after var), start (begin), program (text), read (read/read ln), end (end), the structure is strong, rigorous and tight.

Background

Pascal was invented by Professor Niklaus Wirth of the Federal Institute of Technology in Zurich, Switzerland, in the late 1960s. Designed and created. In 1971, it was named after the computer pioneer Pascal. The Pascal language has strict grammar and was widely welcomed as soon as it was born. It spread quickly from Europe to the United States.

Pascal is based on the ALGOL programming language and is named in honor of the French mathematician and philosopher Blaise Pascal. Wirth later developed the Pascal-like Modula-2 and Oberon. Before developing Pascal, Wirth developed the language Euler and then Algol-W.

Pascal is the earliest structured programming language with rich data types and concise and flexible operation statements. In the development of high-level languages, Pascal is an important milestone. The Pascal language was the first language to systematically embody the concepts of structured programming defined by E.W. Dijkstra and C.A.R. Hoare.

Initially, Pascal was developed largely, but not entirely, to teach students structured programming. Many generations of students have used Pascal as an introductory language in undergraduate courses. Variants of Pascal are increasingly used in everything from research projects to PC games and embedded systems. Newer Pascal compilers exist in areas where it is widely used.

GCC, the Gnu C compiler, was originally written in Pastel, a dialect of Pascal (see GCC# Overview).

Pascal is the high-level language used for Apple Lisa and early Mac development; portions of the original Macintosh operating system were hand-translated from Pascal source code into Motorola 68000 assembly language.

The popular typesetting system TeX was written by Knuth using WEB, the original literary programming system based on DEC PDP-10 Pascal, while applications like Total Commander were written using Delphi (ie Object Pascal).

Object Pascal is still widely used to develop Windows applications like Skype.
