Anders Hejlsberg (/ ˈ h aɪ l z b ɜːr ɡ /, born 2 December 1960) [2] is a Danish software engineer who co-designed several programming languages and development tools. He was the original author of Turbo Pascal and the chief architect of Delphi.
The 1980s were years of relative consolidation in imperative languages. Rather than inventing new paradigms, all of these movements elaborated upon the ideas invented in the prior decade. C++ combined object-oriented and systems programming.
The .NET platform (pronounced as "dot net") is a free and open-source, managed computer software framework for Windows, Linux, and macOS operating systems. [4] The project is mainly developed by Microsoft employees by way of the .NET Foundation and is released under an MIT License.
Programming Languages provides a history and description of 120 programming languages, with an extensive bibliography of reference works about each language and sample programs for many of them. [5] The book outlines both the technical definition and usage of each language, as well as the historical, political, and economic context of each ...
As the languages evolved, the language designers for both languages have faced situations where they wanted to extend the languages with new keywords or syntax. New keywords in particular may break existing code at source level, i.e. older code may no longer compile, if presented to a compiler for a later version of the language.
The language imposes the following restrictions on identifier names: They cannot start with a digit; They cannot start with a symbol, unless it is a keyword; They cannot contain more than 511 characters. Identifier names may be prefixed by an at sign (@), but this is insignificant; @name is the same identifier as name.
