Pascal
Pascal is a general-purpose, high-level language that was originally developed for teaching programming as a systematic discipline and to develop reliable and efficient programs.
Pascal is an Algol-based language and includes many constructs of Algol and Algol 60 is a subset of Pascal. Pascal offers quite a few data types and programming structures, making it is easy to understand and maintain Pascal programs.
Pascal is widely used in the teaching and academics arena for a few reasons:
-
Easy to learn.
-
A structured language.
-
Produces clear, efficient, and reliable programs.
-
Can be compiled on a variety of computer platforms
Pascals features:
-
Pascal is a strongly typed language.
-
Offers extensive error checking.
-
Provides several data types like arrays, records, files, and sets.
-
Provides a variety of programming structures.
-
Supports structured programming through functions and procedures.
-
Supports object-oriented programming.
So why use Pascal?
It allows programmers to define complex structured data types, build dynamic and recursive data structures like lists, hierarchies, search options, calculations, or graphs.
