1 Presentation High-level programming language

2 A programming language is a formal language that specifies a set of instructions that can be used to produce various kinds of output. Programming languages generally consist of instructions for a computer. High-level programming language is a programming language with strong abstraction from the details of the computer. It may use natural language elements, be easier to use, may automate or even hide entirely significant areas of computing systems, making the process of developing a program simpler and more understandable.

3 The first high-level programming language designed for computers was Plankalkül, created by Konrad Zuse. However, it was not implemented in his time due to World War II. First High-level programming languages The first really widespread high-level language was Fortran, defined in 1958 and 1960, by committees of European and American computer scientists, introduced recursion as well as nested functions.

4 Python С# Perl and many others Examples of high-level programming languages in active use today include:

5 Programming language Python Python is a multi-paradigm programming language. Object- oriented programming and structured programming are fully supported, and many of its features support functional programming and aspect-oriented programming (including by metaprogramming and metaobjects). Many other paradigms are supported via extensions, including design by contract and logic programming

6 Python was conceived in the late 1980s as a successor to the ABC language capable of exception handling and interfacing with the Amoeba operating system. Its implementation began in December 1989 by Guido van Rossum. History Van Rossum remains Python's principal author. His continuing central role in Python's development is reflected in the title given to him by the Python community: Benevolent Dictator For Life (BDFL).

7 Guido van Rossum Guido van Rossum is a Dutch programmer who is best known as the author of the Python programming language. He was employed by Google from 2005 until December 2012, where he spent half his time developing the Python language. In January 2013, Van Rossum started working for Dropbox.

8 C# is a multi-paradigm programming language encompassing: strong typing imperative programming declarative programming functional programming generic programming object-oriented programming component-oriented programming Programming language С#

9 In January 1999, Anders Hejlsberg formed a team to build a new language at the time called Cool, which stood for «C-like Object Oriented Language». History Project was publicly announced at the July 2000 Professional Developers Conference, the language had been renamed C#.

10 Anders Hejlsberg Anders Hejlsberg is a prominent Danish software engineer who co-designed several popular and commercially successful programming languages and development tools. He was the original author of Turbo Pascal and the chief architect of Delphi. He currently works for Microsoft as the lead architect of C#.

11 The name «C#» was inspired by musical notation where a «sharp» indicates that the written note should be made a semitone higher in pitch. Name This is similar to the language name of C++, where «++» indicates that a variable should be incremented by 1. The sharp symbol also resembles a ligature of four "+" symbols (in a two-by-two grid), further implying that the language is an increment of C++.

12 Perl is a family of high-level, general-purpose, interpreted, dynamic programming languages. The languages in this family include Perl 5 Perl 6 Programming language Perl Perl was developed in 1987 as a general- purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Perl 6, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally.

13 Larry Wall began work on Perl in 1987, while working as a programmer at Unisys, and released version 1.0 on December 18, The language expanded rapidly over the next few years. History Perl 2, released in 1988, featured a better regular expression engine. Perl 3, released in 1989, added support for binary data streams. Originally, the only documentation for Perl was a single lengthy man page, known to many Perl programmers as the "Camel Book".

14 Larry Wall Larry Wall is a computer programmer and author. He created the Perl programming language. Wall is the author of the Usenet client and the widely used patch program. He has won the International Obfuscated C Code Contest twice and was the recipient of the first Free Software Foundation Award for the Advancement of Free Software in 1998.

15 Language was originally named "Pearl". But then it became known that such a language exists, and the letter "a" was removed. Name A symbol of Perl is a camel. It is not a very beautiful, but very hardy animal, capable of doing hard work.
