  2. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    In the C programming language, data types constitute the semantics and characteristics of storage of data elements. They are expressed in the language syntax in form of declarations for memory locations or variables .

  3. C mathematical functions - Wikipedia

    en.wikipedia.org/wiki/C_mathematical_functions

    C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions. [1] [2] All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions.

  4. long double - Wikipedia

    en.wikipedia.org/wiki/Long_double

    In C and related programming languages, long double refers to a floating-point data type that is often more precise than double precision though the language standard only requires it to be at least as precise as double. As with C's other floating-point types, it may not necessarily map to an IEEE format.

  5. Comparison of programming languages - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_programming...

    Other people's benchmark data may have some value to others, but proper interpretation brings many challenges. The Computer Language Benchmarks Game site warns against over-generalizing from benchmark data, but contains a large number of micro-benchmarks of reader-contributed code snippets, with an interface that generates various charts and ...

  6. Comparison of Pascal and C - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Pascal_and_C

    One of the most important difference between C and Pascal is the way they handle the parameters on stack during a subroutine call : This is called the calling convention : PASCAL-style parameters are pushed on the stack in left-to-right order. The STDCALL calling convention of C pushes the parameters on the stack in right-to-left order.

  7. C (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_(programming_language)

    The language supports a rich set of operators, including bit manipulation, for integer arithmetic and logic, and perhaps different sizes of floating point numbers – it can process appropriately-structured data effectively. C is a fairly small language, with only a handful of statements, and without too many features that generate extensive ...

  8. Function prototype - Wikipedia

    en.wikipedia.org/wiki/Function_prototype

    The term "function prototype" is particularly used in the context of the programming languages C and C++ where placing forward declarations of functions in header files allows for splitting a program into translation units, i.e. into parts that a compiler can separately translate into object files, to be combined by a linker into an executable ...

  9. Mask (computing) - Wikipedia

    en.wikipedia.org/wiki/Mask_(computing)

    In computer science, a mask or bitmask is data that is used for bitwise operations, particularly in a bit field.Using a mask, multiple bits in a byte, nibble, word, etc. can be set either on or off, or inverted from on to off (or vice versa) in a single bitwise operation.
