Origin of the C# Programming language



The name “C sharp” was inspired from musical notation where a sharp indicates that the written note should be made a half-step higher in pitch.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++.

Due to technical limitations of display (standard fonts, browsers, etc.) and the fact that the sharp symbol (♯, U+266F, MUSIC SHARP SIGN) is not present on the standard keyboard, the number sign (#, U+0023, NUMBER SIGN) was chosen to represent the sharp symbol in the written name of the programming language.This convention is reflected in the ECMA-334 C# Language Specification.However, when it is practical to do so (for example, in advertising or in box art), Microsoft uses the intended musical symbol.
