Abbreviation for circa (Latin “about”); used with dates that are uncertain.

A programming language developed by Dennis Ritchie at Bell Laboratories in 1972. It is so named because its immediate predecessor was the B programming language. Although C is considered by many to be more a machine-independent assembly language than a high-level language, its close association with the UNIX operating system, its enormous popularity, and its standardization by the American National Standards Institute (ANSI) have made it perhaps the closest thing to a standard programming language in the microcomputer/workstation marketplace. C is a compiled language that contains a small set of built-in functions that are machine dependent. The rest of the C functions are machine independent and are contained in libraries that can be accessed from C programs. C programs are composed of one or more functions defined by the programmer; thus C is a structured programming language. See also C++, compiled language, library, Objective-C, structured programming.
A general-purpose programing language closely associated with the UNIX operating system.
(computing) High-level general-purpose computer-programming language popular on minicomputers and microcomputers. Developed in the early 1970s from an earlier language called BCPL, C was first used as the language of the operating system Unix, though it has since become widespread beyond Unix. It is useful for writing fast and efficient systems programs, such as operating systems (which control the operations of the computer).

An object-oriented version of the C programming language, developed by Bjarne Stroustrup in the early 1980s at Bell Laboratories and adopted by a number of vendors, including Apple Computer, Inc. and Sun Micro­systems, Inc. See also C, Objective-C, object-oriented programming.
In computing, a high-level programming language used in object-oriented applications. It is derived from the language C.

Carbon

(abbreviation) Abbreviation for centum (Latin “hundred”); century; centigrade; Celsius.

(language) The third letter of the English alphabet. It corresponds to Hebrew gimel and Greek gamma (G, g), both derived from the Semitic word for “camel”. Originally representing a hard g, it was also used by the Romans for k. In English it can have the sound of s or k.

C# is a simple, modern, object oriented and type-safe programming language derived from C and C++.
