data type supported by the C programming language

in some programming languages (C, C++, C#, Java), a variable specially marked to disable optimizations because its value may change between accesses even if it does not appear to be modified; primarily used in hardware access and in threading

'''' is a reserved keyword in the programming languages C, C++, and Objective-C. It is used to create an additional name (alias'') for another data type, but does not create a new type, except in the obscure case of a qualified typedef of an array type where the typedef qualifiers are transferred to the array element type. As such, it is often used to simplify the syntax of declaring complex data structures consisting of struct and union types, although it is also commonly used to provide specific descriptive type names for integer data types of varying sizes.

Pro*C (also known as Pro*C/C++) is an embedded SQL programming language used by Oracle Database DBMSes. Pro*C uses either C or C++ as its host language. During compilation, the embedded SQL statements are interpreted by a precompiler and replaced by C or C++ function calls to their respective SQL library. The output from the Pro*C precompiler is standard C or C++ code that is then compiled by any one of several C or C++ compilers into an executable.

'''''' is a unary operator in the C and C++ programming languages that evaluates to the storage size of an expression or a data type, measured in units sized as char. Consequently, the expression sizeof(char) evaluates to 1. The number of bits of type char is specified by the preprocessor macro CHAR_BIT, defined in the standard include file limits.h|. On most modern computing platforms this is eight bits. The result of sizeof is an unsigned integer that is usually typed as .

extension to the C programming language designed to support parallel programming

(C and C++ programming languages) binary operator that evaluates its first operand and discards the result, and then evaluates the second operand and returns this value (and type); represented by the token ,

data type

CFLAGS and CXXFLAGS are either the name of environment variables or of Makefile variables that can be set to specify additional switches to be passed to a compiler in the process of building computer software. FFLAGS fulfills a similar role.

is a POSIX-defined shell command for generating a C-language flow graph. The GNU implementation reads C source code files, and generates a flow graph of external references. It uses only source files and does not need to run the program. Another implementation is available in Tru64 Unix.

In the C programming language, restrict is a type qualifier that can be applied to a pointer to hint to the compiler that for the lifetime of that pointer, no other pointer will be used to access the same pointed-to object. This limits the effects of pointer aliasing, which can allow the compiler to make optimizations (such as vectorization) that would not otherwise be possible. Undefined behaviour results if the declaration of intent is not followed and the object is accessed by an independent pointer.
