C

a computer programming language combining the advantages of a high-level language with the ability to address the computer at a level comparable with that of an assembly language

C

(language)A programming language designed by Dennis Ritchieat AT&T Bell Labs ca. 1972 for systems programming on thePDP-11 and immediately used to reimplement Unix.

It was called "C" because many features derived from anearlier compiler named "B". In fact, C was briefly named"NB". B was itself strongly influenced by BCPL. BeforeBjarne Stroustrup settled the question by designing C++,there was a humorous debate over whether C's successor shouldbe 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 immenselypopular outside Bell Labs after about 1980 and is now thedominant language in systems and microcomputer applicationsprogramming. It has grown popular due to its simplicity,efficiency, and flexibility. C programs are often easilyadapted to new environments.

C is often described, with a mixture of fondness and disdain,as "a language that combines all the elegance and power ofassembly language with all the readability andmaintainability of assembly language".

Ritchie's original C, known as K&R C after Kernighan andRitchie's book, has been standardised (and simultaneouslymodified) as ANSI C.

C

(1) See coulomb.

(2) A high-level programming language developed at Bell Labs that is also able to manipulate the computer at a low level like assembly language. Developed in the 1970s, by the end of the 1980s, C became the language of choice for developing commercial software. C, and its object-oriented successor C++, are used to write a huge variety of applications and almost all operating systems. There are C/C++ compilers for all major operating systems and hardware platforms. C was standardized by ANSI (X3J11 committee) and ISO in 1989.

C++ (C Plus Plus)
Created by Bjarne Stroustrup in 1983, C++ added object-oriented programming (OOP) to C. Originally called "C with Classes," C++ became the standard C language, often designated as C/C++. In contrast, Smalltalk and other object-oriented languages did not provide the familiar structures of conventional languages such as C and Pascal. See object-oriented programming, Smalltalk, Visual C++, Objective-C, C# and Managed C++.

Nothing But Functions
C and C++ are written as a series of functions that call each other for processing. Even the body of the program is a function named "main." Functions are very flexible, allowing programmers to choose from the standard library that comes with the compiler, to use third party libraries or to develop their own.

Its Origin
C was developed to allow Unix to run on a variety of computers. After Bell Labs' Ken Thompson and Dennis Ritchie created Unix and got it running on several PDP computers, they wanted a way to easily port it to other machines without having to rewrite it from scratch. Thompson created the B language, which was a simpler version of the BCPL language, itself a version of CPL. Later, in order to improve B, Thompson and Ritchie created C.

The following examples convert Fahrenheit to centigrade in C and C++. For another example of C code, see event loop.

 In C main() { float fahr; printf("Enter Fahrenheit: "); scanf("%f", &fahr); printf("Celsius is %f\", (fahr-32)*5/9); } In C++ void main() { float fahr; cout << "Enter Fahrenheit: "; cin >> fahr; fahr = (((fahr-32)*5)/9); cout << "Celsius = " << fahr << endl; return 0; }
