Vala, Verilog HDL4C, as in the letter c is a general purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, and therefore it has found lasting use in applications that had formerly been coded in assembly language, including operating systems, as well as various application software for computers ranging from supercomputers to embedded systems. C was originally developed by Dennis Ritchie between 1. Bell Labs,5 and used to re implement the Unix operating system. 6 It has since become one of the most widely used programming languages of all time,78 with C compilers from various vendors available for the majority of existing computer architectures and operating systems. C has been standardized by the American National Standards Institute ANSI since 1. ANSI C and subsequently by the International Organization for Standardization ISO. C is an imperativeprocedural language. It was designed to be compiled using a relatively straightforward compiler, to provide low level access to memory, to provide language constructs that map efficiently to machine instructions, and to require minimal run time support. Despite its low level capabilities, the language was designed to encourage cross platform programming. A standards compliant and portably written C program can be compiled for a very wide variety of computer platforms and operating systems with few changes to its source code. The language has become available on a very wide range of platforms, from embedded microcontrollers to supercomputers. Overview. Like most imperative languages in the ALGOL tradition, C has facilities for structured programming and allows lexical variable scope and recursion, while a static type system prevents many unintended operations. In C, all executable code is contained within subroutines, which are called functions although not in the strict sense of functional programming. Function parameters are always passed by value. Pass by reference is simulated in C by explicitly passing pointer values. C program source text is free format, using the semicolon as a statement terminator and curly braces for grouping blocks of statements. The C language also exhibits the following characteristics There is a small, fixed number of keywords, including a full set of flow of control primitives for, ifelse, while, switch, and dowhile. User defined names are not distinguished from keywords by any kind of sigil. There are a large number of arithmetical and logical operators, such as, ,, ,, etc. More than one assignment may be performed in a single statement. Function return values can be ignored when not needed. Typing is static, but weakly enforced all data has a type, but implicit conversions may be performed. Declarationsyntax mimics usage context. C has no define keyword instead, a statement beginning with the name of a type is taken as a declaration. There is no function keyword instead, a function is indicated by the parentheses of an argument list. User defined typedef and compound types are possible. Heterogeneous aggregate data types struct allow related data elements to be accessed and assigned as a unit. Array indexing is a secondary notation, defined in terms of pointer arithmetic. Unlike structs, arrays are not first class objects they cannot be assigned or compared using single built in operators. There is no array keyword, in use or definition instead, square brackets indicate arrays syntactically, for example month1. Enumerated types are possible with the enum keyword. They are not tagged, and are freely interconvertible with integers. Strings are not a separate data type, but are conventionally implemented as null terminated arrays of characters. Low level access to computer memory is possible by converting machine addresses to typed pointers. Procedures subroutines not returning values are a special case of function, with an untyped return type void. Functions may not be defined within the lexical scope of other functions. Function and data pointers permit ad hocrun time polymorphism. A preprocessor performs macro definition, source code file inclusion, and conditional compilation. There is a basic form of modularity files can be compiled separately and linked together, with control over which functions and data objects are visible to other files via static and extern attributes. Complex functionality such as IO, string manipulation, and mathematical functions are consistently delegated to library routines. While C does not include some features found in some other languages, such as object orientation or garbage collection, such features can be implemented or emulated in C, often by way of external libraries e. Boehm garbage collector or the GLib Object System. Relations to other languages. Many later languages have borrowed directly or indirectly from C, including C, D, Go, Rust, Java, Java. Script, Limbo, LPC, C, Objective C, Perl, PHP, Python, Swift, Verilog hardware description language,4 and Unixs C shell. These languages have drawn many of their control structures and other basic features from C. Most of them with Python being the most dramatic exception are also very syntactically similar to C in general, and they tend to combine the recognizable expression and statement syntax of C with underlying type systems, data models, and semantics that can be radically different. History. Early developments. The origin of C is closely tied to the development of the Unix operating system, originally implemented in assembly language on a PDP 7 by Dennis Ritchie and Ken Thompson, incorporating several ideas from colleagues. Eventually, they decided to port the operating system to a PDP 1. The original PDP 1. Unix was developed in assembly language. The developers were considering rewriting the system using the B language, Thompsons simplified version of BCPL. 9 However Bs inability to take advantage of some of the PDP 1. C. The name of C was chosen simply as the next after B. 1. The development of C started in 1. PDP 1. 1 Unix system1. Version 2 Unix. 1. The language was not initially designed with portability in mind, but soon ran on different platforms as well a compiler for the Honeywell 6. Cs history, while an IBM System3. Also in 1. 97. 2, a large part of Unix was rewritten in C. 1. By 1. 97. 3, with the addition of struct types, the C language had become powerful enough that most of the Unixkernel was now in C.
