A "Hello, World!" program is generally a simple computer program which emits (or displays) to the screen (often the console) a message similar to "Hello, World!" while ignoring any user input. A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.
C ( pronounced / ˈsiː / – like the letter c) [ 6 ] is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems code (especially in kernels [ 7 ...
program, which prints only the text "hello, world" as an illustration of a minimal working C program. Since then, many texts have followed that convention for introducing a programming language. Before the advent of ANSI C, the first edition of the text served as the de facto standard of the language for writers of C compilers. With the ...
Brainfuck. Brainfuck is an esoteric programming language created in 1993 by Swiss physics student Urban Müller. [ 1] Designed to be extremely minimalistic, the language consists of only eight simple commands, a data pointer and an instruction pointer. [ 2]
Whitespace is an esoteric programming language with syntax where only whitespace characters ( space, tab and linefeed) have meaning – contrasting typical languages that largely ignore whitespace characters. [ 1][ 2] As a consequence of its syntax, Whitespace source code can be contained within the whitespace of code written in a language that ...
Malbolge has three registers, a, c, and d. When a program starts, the value of all three registers is zero. a stands for 'accumulator', set to the value written by all write operations on memory and used for standard I/O. c, the code pointer, is special: it points to the current instruction. [12] d is the data pointer. It is automatically ...
Piet program that prints 'Piet' A "Hello World" program in Piet. Piet is a language designed by David Morgan-Mar, whose programs are bitmaps that look like abstract art. [29] The execution is guided by a "pointer" that moves around the image, from one continuous coloured region to the next. Procedures are carried out when the pointer exits a ...
C++ inherits most of C's syntax. A hello world program that conforms to the C standard is also a valid C++ hello word program. The following is Bjarne Stroustrup's version of the Hello world program that uses the C++ Standard Library stream facility to write a message to standard output: [61] [62] [note 2]
