Williams. \"Hello, World!\" program_sentence_23\n\nVariations \"Hello, World!\" program_section_1\n\n\"Hello, World!\" \"Hello, World!\" program_sentence_24\n\nprograms vary in complexity between different languages. \"Hello, World!\" program_sentence_25\n\nIn some languages, particularly scripting languages, the \"Hello, World!\" \"Hello, World!\" program_sentence_26\n\nprogram can be written as a single statement, while in others (particularly many low-level languages) there can be many more statements required. \"Hello, World!\" program_sentence_27\n\nFor example, in Python, to print the string Hello, World! \"Hello, World!\" program_sentence_28\n\nfollowed by a newline, one need only write print(\"Hello, World!\"). \"Hello, World!\" program_sentence_29\n\nIn contrast, the equivalent code in C++ requires the import of the input/output software library, the manual declaration of an entry point, and the explicit instruction that the output string should be sent to the standard output stream. \"Hello, World!\" program_sentence_30\n\nGenerally, programming languages that give the programmer more control over the machine will result in more complex \"Hello, World\" programs. \"Hello, World!\" program_sentence_31\n\nThe phrase \"Hello World!\" \"Hello, World!\" program_sentence_32\n\nhas seen various deviations in punctuation and casing, such as the presence of the comma and exclamation mark, and the capitalization of the leading H and W. Some devices limit the format to specific variations, such as all-capitalized versions on systems that support only capital letters, while some esoteric programming languages may have to print a slightly modified string. \"Hello, World!\" program_sentence_33\n\nFor example, the first non-trivial Malbolge program printed \"HEllO WORld\", this having been determined to be good enough. \"Hello, World!\" program_sentence_34\n\nOther human languages have been used as the output; for example, a tutorial for the Go programming language outputted both English and Chinese characters, demonstrating the programming language's built-in Unicode support. \"Hello, World!\" program_sentence_35\n\nSome languages change the functionality of the \"Hello, World!\" \"Hello, World!\" program_sentence_36\n\nprogram while maintaining the spirit of demonstrating a simple example. \"Hello, World!\" program_sentence_37\n\nFunctional programming languages, such as Lisp, ML and Haskell, tend to substitute a factorial program for \"Hello, World! \"Hello, World!\" program_sentence_38\n\n\", as functional programming emphasizes recursive techniques, whereas the original examples emphasize I/O, which violates the spirit of pure functional programming by producing side effects. \"Hello, World!\" program_sentence_39\n\nLanguages otherwise capable of printing \"Hello, World!\" \"Hello, World!\" program_sentence_40\n\n(Assembly, C, VHDL) may also be used in embedded systems, where text output is either difficult (requiring additional components or communication with another computer) or nonexistent. \"Hello, World!\" program_sentence_41\n\nFor devices such as microcontrollers, field-programmable gate arrays, and CPLDs, \"Hello, World!\" \"Hello, World!\" program_sentence_42\n\nmay thus be substituted with a blinking LED, which demonstrates timing and interaction between components. \"Hello, World!\" program_sentence_43\n\nThe Debian and Ubuntu Linux distributions provide the \"Hello, World!\" \"Hello, World!\" program_sentence_44\n\nprogram through their software package manager systems, which can be invoked with the command hello. \"Hello, World!\" program_sentence_45\n\nIt serves as a sanity check and a simple example of installing a software package. \"Hello, World!\" program_sentence_46\n\nFor developers, it provides an example of creating a .deb package, either traditionally or using debhelper, and the version of hello used, GNU Hello, serves as an example of writing a GNU program. \"Hello, World!\" program_sentence_47\n\nVariations of the \"Hello, World!\" \"Hello, World!\" program_sentence_48\n\nprogram that produce a graphical output (as opposed to text output) have also been shown. \"Hello, World!\" program_sentence_49\n\nSun demonstrated a \"Hello, World!\" \"Hello, World!\" program_sentence_50\n\nprogram in Java based on scalable vector graphics, and the XL programming language features a spinning Earth \"Hello, World!\" \"Hello, World!\" program_sentence_51\n\nusing 3D computer graphics. \"Hello, World!\" program_sentence_52\n\nMark Guzdial and Elliot Soloway have suggested that the \"hello, world\" test message may be outdated now that graphics and sound can be manipulated as easily as text. \"Hello, World!\" program_sentence_53\n\nTime to Hello World \"Hello, World!\" program_section_2\n\n\"Time to hello world\" (TTHW) is the time it takes to author a \"Hello, World!\" \"Hello, World!\" program_sentence_54\n\nprogram in a given programming language. \"Hello, World!\" program_sentence_55\n\nThis is one measure of a programming language's ease-of-use; since the program is meant as an introduction for people unfamiliar with the language, a more complex \"Hello, World!\" \"Hello, World!\" program_sentence_56\n\nprogram may indicate that the programming language is less approachable. \"Hello, World!\" program_sentence_57\n\nThe concept has been extended beyond programming languages to APIs, as a measure of how simple it is for a new developer to get a basic example working; a faster time indicates an easier API for developers to adopt. \"Hello, World!\" program_sentence_58\n\nSee also \"Hello, World!\" program_section_3\n\n\"Hello, World!\" program_unordered_list_0\n\n  * C (programming language) § \"Hello, world\" example\"Hello, World!\" program_item_0_0\n  * \"99 Bottles of Beer\" as used in computer science\"Hello, World!\" program_item_0_1\n  * Foobar\"Hello, World!\" program_item_0_2\n  * Bad Apple!!
