  2. Dynamic array - Wikipedia

    en.wikipedia.org/wiki/Dynamic_array

    The logical size and capacity of the final array are shown. In computer science, a dynamic array, growable array, resizable array, dynamic table, mutable array, or array list is a random access, variable-size list data structure that allows elements to be added or removed. It is supplied with standard libraries in many modern mainstream ...

  3. Array (data structure) - Wikipedia

    en.wikipedia.org/wiki/Array_(data_structure)

    Array (data structure) In computer science, an array is a data structure consisting of a collection of elements ( values or variables ), of same memory size, each identified by at least one array index or key. An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula.

  4. NumPy - Wikipedia

    en.wikipedia.org/wiki/NumPy

    numpy .org. NumPy (pronounced / ˈnʌmpaɪ / NUM-py) is a library for the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions to operate on these arrays. [3] The predecessor of NumPy, Numeric, was originally created by Jim Hugunin with ...

  5. Enumerated type - Wikipedia

    en.wikipedia.org/wiki/Enumerated_type

    Enumerated type. In computer programming, an enumerated type (also called enumeration, enum, or factor in the R programming language, and a categorical variable in statistics) is a data type consisting of a set of named values called elements, members, enumeral, or enumerators of the type. The enumerator names are usually identifiers that ...

  6. Boolean data type - Wikipedia

    en.wikipedia.org/wiki/Boolean_data_type

    Boolean data type. In computer science, the Boolean (sometimes shortened to Bool) is a data type that has one of two possible values (usually denoted true and false) which is intended to represent the two truth values of logic and Boolean algebra. It is named after George Boole, who first defined an algebraic system of logic in the mid 19th ...

  7. Variable-length array - Wikipedia

    en.wikipedia.org/wiki/Variable-length_array

    Variable-length array. In computer programming, a variable-length array ( VLA ), also called variable-sized or runtime-sized, is an array data structure which length is determined at runtime, instead of at compile time. [1] In the language C, the VLA is said to have a variably modified data type that depends on a value (see Dependent type ).

  8. typedef - Wikipedia

    en.wikipedia.org/wiki/Typedef

    typedef 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.

  9. Array (data type) - Wikipedia

    en.wikipedia.org/wiki/Array_(data_type)

    In computer science, array is a data type that represents a collection of elements ( values or variables ), each selected by one or more indices (identifying keys) that can be computed at run time during program execution. Such a collection is usually called an array variable or array value. [1] By analogy with the mathematical concepts vector ...
