Q&A

Why Pascal is not used?

Why Pascal is not used?

Pascal was originally intended primarily as a teaching language, but it has been more and more often recommended as a language for serious programming as well, for example, for system programming tasks and even operating systems. Pascal, at least in its standard form, is just plain not suitable for serious programming.

Is Pascal a system programming language?

Pascal was influenced by the ALGOL W efforts, with the explicit goals of teaching programming in a structured fashion and for the development of system software. Apollo Computer used Pascal as the systems programming language for its operating systems beginning in 1980.

Why is Pascal safer than C?

In its original form (as described by Niklaus Wirth), Pascal qualifies as a managed pointer language, some 30 years before either Java or C#. However, a Pascal amalgamated with C would lose that protection by definition. In general, the lower dependence on pointers for basic tasks makes it safer than C in practice.

What is good about Pascal?

Pascal allows the programmers to define complex structured data types and build dynamic and recursive data structures, such as lists, trees and graphs. Pascal offers features like records, enumerations, subranges, dynamically allocated variables with associated pointers and sets.

What happened Pascal language?

The people that say Pascal (or Delphi) are dead, usually are very ignorant about the language, its evolution, and its many dialects.

Is Pascal high level?

Pascal is a general-purpose, high-level language that was originally developed by Niklaus Wirth in the early 1970s. It was developed for teaching programming as a systematic discipline and to develop reliable and efficient programs. It is easy to understand and maintain the Pascal programs.

Is Pascal programming still used?

Developed in the late 1960s, Pascal is an imperative and procedural programming language that was originally designed for teaching programming languages. Today, it’s been mostly replaced by C, C++ and Java, but it’s still used as an introduction to programming.

What is the Pascal programming language used for?

Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal.

What is the difference between C and Pascal?

Unlike C (and most languages in the C-family ), Pascal allows nested procedure definitions to any level of depth, and also allows most kinds of definitions and declarations inside subroutines (procedures and functions). A program is thus syntactically similar to a single procedure or function.

What is the use of Pascal XSC?

Pascal-XSC has at various times been ported to Unix (Linux, SunOS, HP-UX, AIX) and Microsoft/IBM (DOS with EMX, OS/2, Windows) operating systems. It operates by generating intermediate C source code which is then compiled to a native executable. Some of the Pascal-SC language extensions have been adopted by GNU Pascal .

What is the difference between Pascal P4 and Pascal P5?

The Pascal-P4 compiler–interpreter can still be run and compiled on systems compatible with original Pascal. However, it only accepts a subset of the Pascal language. Pascal-P5, created outside the Zürich group, accepts the full Pascal language and includes ISO 7185 compatibility.
