In some languages, particularly scripting languages, the "Hello, World!" program can be written as one statement, while in others (more so many low-level languages) many more statements can be required. For example, in Python, to print the string Hello, World! followed by a newline, one only needs to write print ("Hello, World!").
The "Hello world" program uses printf in its simplest form: by simply passing it a string with no special formatting codes, and no extra arguments. The input text is simply printed to the screen. (Note that the "\n" special escape sequence is converted into a newline character.)
Original – The first known version "Hello, World!" program by Brian Kernighan from Artsy's Algorythm Auction based on a 1974 Bell Laboratories internal memorandum, "Programming in C: A Tutorial". Reason High quality file of historical value, excellent EV and importance in the computing and programming. Articles in which this image appears ...
A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.
"Hello, World!" program by Brian Kernighan (1978) The "hello, world" example that appeared in the first edition of K&R has become the model for an introductory program in most programming textbooks. The program prints "hello, world" to the standard output, which is usually a terminal or screen display. The original version was: [36]
In 1972, Kernighan described memory management in strings using "hello" and "world", in the B programming language, [19] which became the iconic example we know today. Kernighan's original 1978 implementation of hello, world! was sold at The Algorithm Auction , the world's first auction of computer algorithms .
