Pascal Interview Questions

In simple words, Pascal is a programming language that supports programming structured and data structures. It is a third-generation language designed for instructional purposes. The language is developed by Niklaus Wirth in 1971 and is named after the Mathematician scientist Blaise Pascal. One pascal is equivalent to one newton (1 N) of force applied over an area of one meter squared, that is (1 Pa = 1 N . m-2). Mentioned below are some of the Pascal Triangle Interview Questions that will help you get the right knowledge.

Most Frequently Asked Pascal Interview Questions

Here in this article, we will be listing frequently asked Pascal Interview Questions and Answers with the belief that they will be helpful for you to gain higher marks. Also, to let you know that this article has been written under the guidance of industry professionals and covered all the current competencies.

Q21. What is the process to perform string operations in Pascal?

Firstly Pascal can’t handle the string of characters and it is one of the top disadvantages of the language.

Q22. What are the reasons for using UNITS in programming?
  • It is easier to handle large programs because by using Units it splits into a smaller section
  • By adding UNITS, one can use the same code in some other program to do the same job.
  • If you put a code in a unit, it becomes easy to call and use it again.

Key features of pascal programming language

  • High speed and low memory use
  • Great Integration with assembler
  • Distribution Independence
  • Each unit has its own identifiers
  • Very clean language
  • Object-Oriented programming

Development History

  • The programming language was designed by Niklaus Wirth in 1968-1969 and it was published in 1970.
  • ALGOL 60 pattern is similar to the Pascal Language on which it is developed.
  • Its Object-oriented programming version was launched in 1985.

Some programmers feel that Pascal is too restrictive in its rules and doesn't allow a programmer to state new rules. But eventually, it started providing simplicity and a modular approach for machine implementation. You will get to know about this when you start reading pascal interview questions and answers that we are mentioning down below. Modern Pascal uses more securities and fewer ambiguities while programming or coding and still used as an instructional language.

Latest Version: The latest version of Free Pascal is version 3.0.4 and development releases version numbers 3.1.x.
