A programming language developed in 1972 and commonly used for writing professional software. With only a small number of built-in functions, it requires less memory than other languages, and because most if its functions are not specific to particular computers, it can be used on many different kinds of machines. The Unix operating system was written in C.
carbonAudio Help (kär'bən) Pronunciation Key Symbol C
A naturally abundant, nonmetallic element that occurs in all organic compounds and can be found in all known forms of life. Diamonds and graphite are pure forms, and carbon is a major constituent of coal, petroleum, and natural gas. Carbon generally forms four covalent bonds with other atoms in larger molecules. Atomic number 6; atomic weight 12.011; sublimation point above 3,500°C; boiling point 4,827°C; specific gravity of amorphous carbon 1.8 to 2.1, of diamond 3.15 to 3.53, of graphite 1.9 to 2.3; valence 2, 3, 4. See Periodic Table.
Clanguage A programming language designed by Dennis Ritchie at AT&TBell Labs ca. 1972 for systems programming on the PDP-11 and immediately used to reimplement Unix. It was called "C" because many features derived from an earlier compiler named "B". In fact, C was briefly named "NB". B was itself strongly influenced by BCPL. Before Bjarne Stroustrup settled the question by designing C++, there was a humorous debate over whether C's successor should be named "D" or "P" (following B and C in "BCPL"). C is terse, low-level and permissive. It has a macro preprocessor, cpp. Partly due to its distribution with Unix, C became immensely popular outside Bell Labs after about 1980 and is now the dominant language in systems and microcomputer applications programming. It has grown popular due to its simplicity, efficiency, and flexibility. C programs are often easily adapted to new environments. C is often described, with a mixture of fondness and disdain, as "a language that combines all the elegance and power of assembly language with all the readability and maintainability of assembly language". Ritchie's original C, known as K&R C after Kernighan and Ritchie's book, has been standardised (and simultaneously modified) as ANSI C. See also ACCU, ae, c68, c386, C-Interp, cxref, dbx, dsp56k-gcc, dsp56165-gcc, gc, GCT, GNU C, GNU superoptimiser, Harvest C, malloc, mpl, Pthreads, ups. [The Jargon File] (1996-06-01)
C\ (s[=e]) 1. C is the third letter of the English alphabet. It is from the Latin letter C, which in old Latin represented the sounds of k, and g (in go); its original value being the latter. In Anglo-Saxon words, or Old English before the Norman Conquest, it always has the sound of k. The Latin C was the same letter as the Greek [Gamma], [gamma], and came from the Greek alphabet. The Greeks got it from the Ph[oe]nicians. The English name of C is from the Latin name ce, and was derived, probably, through the French. Etymologically C is related to g, h, k, q, s (and other sibilant sounds). Examples of these relations are in L. acutus, E. acute, ague; E. acrid, eager, vinegar; L. cornu, E. horn; E. cat, kitten; E. coy, quiet; L. circare, OF. cerchier, E. search. Note: See Guide to Pronunciation, [sect][sect] 221-228. 2. (Mus.) (a) The keynote of the normal or "natural" scale, which has neither flats nor sharps in its signature; also, the third note of the relative minor scale of the same. (b) C after the clef is the mark of common time, in which each measure is a semibreve (four fourths or crotchets); for alla breve time it is written ?. (c) The "C clef," a modification of the letter C, placed on any line of the staff, shows that line to be middle C. 3. As a numeral, C stands for Latin centum or 100, CC for 200, etc. C spring, a spring in the form of the letter C.
