It is often considered to be tradition among programmers for people attempting to learn a new programming language to write a "Hello World!" program as one of the first steps of learning that particular language. Some are surprisingly complex, especially in some graphical user interface (GUI) contexts, but most are very simple, especially those which rely heavily on a particular command line interpreter ("shell") to perform the actual output. .In an embedded system, the text may be sent to a liquid crystal display (LCD), or the message may be substituted by some other appropriate signal, such as an LED being turned on.^ In an embedded system, the text may be sent to a liquid crystal display (LCD), or the message may be substituted by some other appropriate signal, such as a LED being turned on.

History

While small test programs existed since the development of programmable computers, the tradition of using the phrase "Hello world!" as a test message was influenced by an example program in the seminal book The C Programming Language. The example program from that book prints "hello, world" (without capital letters or exclamation mark), and was inherited from a 1974 Bell Laboratories internal memorandum by Brian Kernighan, Programming in C: A Tutorial, which contains the first known version:
 int main() 
 {
        printf("hello, world");
        return 0;
 }
The first known instance of the usage of the words "hello" and "world" together in computer literature occurred earlier, in Kernighan's 1972 Tutorial Introduction to the Language B[1], with the following code:
main( ) {
  extrn a, b, c;
  putchar(a); putchar(b); putchar(c); putchar('!*n');
}
a 'hell';
b 'o, w';
c 'orld';

Variations

.There are many variations on the punctuation and casing of the phrase.^ Session State There have been so many occasions where I wished I could use the ASP Session variables, only to realize that the application will be running on a WebFarm without server affinity.
  • ASP 101 - Articles 2 February 2010 8:08 UTC www.asp101.com [Source type: FILTERED WITH BAYES]

.Variations include the presence or absence of the comma and exclamation mark, and the capitalization of the 'H', both the 'H' and the 'W', or neither.^ Opinion is divided on whether there should be an exclamation mark at the end of the phrase, a comma after 'hello', and if either or both of the words should be capitalised, lower case or mixed case.
