The function body consists of a single statement, a call to the printf() function, which stands for "print formatted"; it outputs to the console whatever is passed to it as the parameter, in this case the string "hello, world". The C-language version was preceded by Kernighan's own 1972 A Tutorial Introduction to the Language B, [4] where the ...
A conversation with Eliza. ELIZA is an early natural language processing computer program developed from 1964 to 1967 [1] at MIT by Joseph Weizenbaum. [2] [3] Created to explore communication between humans and machines, ELIZA simulated conversation by using a pattern matching and substitution methodology that gave users an illusion of understanding on the part of the program, but had no ...
Alan Turing is credited with being the first person to come up with a theory for software in 1935, which led to the two academic fields of computer science and software engineering. The first generation of software for early stored-program digital computers in the late 1940s had its instructions written directly in binary code, generally ...

PLATO Notes, created by David R. Woolley in 1973, was among the world's first online message boards, and years later became the direct progenitor of Lotus Notes. [ citation needed ] PLATO's plasma panels were well suited to games, although its I/O bandwidth (180 characters per second or 60 graphic lines per second) was relatively slow.
The draughts program failed due to program errors when it first ran at NPL on 30 July 1951. [8] When Strachey heard about the Manchester Mark 1, which had a much bigger memory, he asked his former fellow-student Alan Turing for the manual and transcribed his program into the operation codes of that machine by around October 1951. By the summer ...
The cover of the book The C Programming Language, first edition, by Brian Kernighan and Dennis Ritchie. In 1978 Brian Kernighan and Dennis Ritchie published the first edition of The C Programming Language. [18] Known as K&R from the initials of its authors, the book served for many years as an informal specification of the language.
Simula, invented in the late 1960s by Nygaard and Dahl as a superset of ALGOL 60, was the first language designed to support object-oriented programming. FORTH , the earliest concatenative programming language was designed by Charles Moore in 1969 as a personal development system while at the National Radio Astronomy Observatory (NRAO).
