Vala, Verilog (HDL)[4]C (, 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,[7][8] 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 imperative (procedural) 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. Therefore, C was useful for many applications that had formerly been coded in assembly language, for example in system programming. 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[edit]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. To demonstrate how to extend Qt with plugins, we will implement two plugins in this section. The first is a very simple QStyle plugin for the Bronze style.

Financial Numerical Recipes in C++: Applications in Finance. This book provides a good deal of useful examples and. 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, if/else, while, switch, and do/while. There is one namespace, and 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 can be performed; for instance, characters can be used as integers. 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 month[1. 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 I/O, string manipulation, and mathematical functions are consistently delegated to library routines. C does not include some features found in newer, more modern high- level languages, including object orientation and garbage collection. Relations to other languages[edit]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, Verilog (hardware description language),[4] and Unix's 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[edit]Early developments[edit]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 Ritchie and 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, Thompson's simplified version of BCPL.[9] However B's inability to take advantage of some of the PDP- 1. C. The development of C started in 1. PDP- 1. 1 Unix system[1. 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. C's history, while an IBM System/3. The name of C simply continued the alphabetic order started by B.[1. 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 Unix's kernel was now in C. Unix was one of the first operating system kernels implemented in a language other than assembly. Earlier instances include the Multics system (written in PL/I), and MCP (Master Control Program) for the Burroughs B5. ALGOL in 1. 96. 1.) Circa 1. Ritchie and Stephen C. Johnson made further changes to the language to facilitate portability of the Unix operating system. Johnson's Portable C Compiler served as the basis for several implementations of C on new platforms.[1. In 1. 97. 8, Brian Kernighan and Dennis Ritchie published the first edition of The C Programming Language.[1] This book, known to C programmers as "K& R", served for many years as an informal specification of the language. The version of C that it describes is commonly referred to as K& R C. The second edition of the book[1. ANSI C standard, described below. K& R introduced several language features: Standard I/O librarylong int data typeunsigned int data type. Compound assignment operators of the form =op (such as =- ) were changed to the form op= (that is, - =) to remove the semantic ambiguity created by constructs such as i =- 1. Even after the publication of the 1. ANSI standard, for many years K& R C was still considered the "lowest common denominator" to which C programmers restricted themselves when maximum portability was desired, since many older compilers were still in use, and because carefully written K& R C code can be legal Standard C as well. In early versions of C, only functions that returned a non- int value needed to be declared if used before the function definition; a function used without any previous declaration was assumed to return type int, if its value was used. For example: longsome_function(); /* int */other_function(); /* int */calling_function(){longtest. The int type specifiers which are commented out could be omitted in K& R C, but are required in later standards. Since K& R function declarations did not include any information about function arguments, function parameter type checks were not performed, although some compilers would issue a warning message if a local function was called with the wrong number of arguments, or if multiple calls to an external function used different numbers or types of arguments. Separate tools such as Unix's lint utility were developed that (among other things) could check for consistency of function use across multiple source files.
