C Sharp [C#] Programming Practical Tests and Questions
Welcome to The HOT language !! C# Test SIMULATOR Top tests and questions with Detailed Answers
C# is a general-purpose, multi-paradigm programming language. C# encompasses static typing, strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines.
C# was designed by Anders Hejlsberg from Microsoft in 2000 and was later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO (ISO/IEC 23270) in 2003. Microsoft introduced C# along with .NET Framework and Visual Studio, both of which were closed-source. At the time, Microsoft had no open-source products. Four years later, in 2004, a free and open-source project called Mono began, providing a cross-platform compiler and runtime environment for the C# programming language. A decade later, Microsoft released Visual Studio Code (code editor), Roslyn (compiler), and the unified .NET platform (software framework), all of which support C# and are free, open-source, and cross-platform. Mono also joined Microsoft but was not merged into .NET.
Microsoft first used the name C# in 1988 for a variant of the C language designed for incremental compilation. That project was not completed but the name lives on.
The name “C sharp” was inspired by the musical notation whereby a sharp symbol indicates that the written note should be made a semitone higher in pitch. This is similar to the language name of C++, where “++” indicates that a variable should be incremented by 1 after being evaluated. 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++.
Due to technical limitations of display (standard fonts, browsers, etc.) and the fact that the sharp symbol (U+266F ♯ MUSIC SHARP SIGN (HTML ♯ · ♯)) is not present on most keyboard layouts, the number sign (U+0023 # NUMBER SIGN (HTML # · & num;)) was chosen to approximate the sharp symbol in the written name of the programming language. This convention is reflected in the ECMA-334 C# Language Specification.
The “sharp” suffix has been used by a number of other .NET languages that are variants of existing languages, including J# (a .NET language also designed by Microsoft that is derived from Java 1.1), A# (from Ada), and the functional programming language F#. The original implementation of Eiffel for .NET was called Eiffel#, a name retired since the full Eiffel language is now supported. The suffix has also been used for libraries, such as Gtk# (a .NET wrapper for GTK and other GNOME libraries) and Cocoa# (a wrapper for Cocoa).
