| carbon (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. carbonaceous adjective |
| colon (kō'lən) Pronunciation Key
The longest part of the large intestine, extending from the cecum to the rectum. Water and electrolytes are absorbed, solidified, and prepared for elimination as feces in the colon. The colon also contains bacteria that help in the body's absorption of nutrients from digested material. |
| Coulomb, Charles Augustin de 1736-1806.
French physicist who was a pioneer in the study of magnetism and electricity. He is best known for the formulation of Coulomb's law, which he developed as a result of his investigations of Joseph Priestley's work on electrical repulsion. Coulomb also established a law governing the attraction and repulsion of magnetic poles. The coulomb unit of electric charge is named for him. |
C language
A programming language designed by Dennis Ritchie at AT&T Bell 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.
