  2. struct (C programming language) - Wikipedia

    en.wikipedia.org/wiki/Struct_(C_programming...

    In the C programming language, struct is the keyword used to define a composite, a.k.a. record, data type – a named set of values that occupy a block of memory. It allows for the different values to be accessed via a single identifier, often a pointer. A struct can contain other data types so is used for mixed-data-type records.

  3. List of data structures - Wikipedia

    en.wikipedia.org/wiki/List_of_data_structures

    Array, a sequence of elements of the same type stored contiguously in memory; Record (also called a structure or struct), a collection of fields Product type (also called a tuple), a record in which the fields are not named; String, a sequence of characters representing text; Union, a datum which may be one of a set of types

  4. Array (data type) - Wikipedia

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

    An array data structure can be mathematically modeled as an abstract data structure (an abstract array) with two operations get(A, I): the data stored in the element of the array A whose indices are the integer tuple I. set(A, I, V): the array that results by setting the value of that element to V. These operations are required to satisfy the ...

  5. Associative containers (C++) - Wikipedia

    en.wikipedia.org/wiki/Associative_containers_(C++)

    The key is used to order the sequence, and the value is somehow associated with that key. For example, a map might contain keys representing every unique word in a text and values representing the number of times that word appears in the text. A set is simply an ascending container of unique elements. As stated earlier, map and set only allow ...

  6. Data structure alignment - Wikipedia

    en.wikipedia.org/wiki/Data_structure_alignment

    Data structure alignment is the way data is arranged and accessed in computer memory. It consists of three separate but related issues: data alignment , data structure padding , and packing . The CPU in modern computer hardware performs reads and writes to memory most efficiently when the data is naturally aligned , which generally means that ...

  7. C++ classes - Wikipedia

    en.wikipedia.org/wiki/C++_classes

    A class in C++ is a user-defined type or data structure declared with any of the keywords class, struct or union (the first two are collectively referred to as non-union classes) that has data and functions (also called member variables and member functions) as its members whose access is governed by the three access specifiers private, protected or public.

  8. Initialization (programming) - Wikipedia

    en.wikipedia.org/wiki/Initialization_(programming)

    In C++, a constructor of a class/struct can have an initializer list within the definition but prior to the constructor body. It is important to note that when you use an initialization list, the values are not assigned to the variable. They are initialized. In the below example, 0 is initialized into re and im. Example:

  9. Composite data type - Wikipedia

    en.wikipedia.org/wiki/Composite_data_type

    In computer science, a composite data type or compound data type is a data type that consists of programming language scalar data types and other composite types that may be heterogeneous and hierarchical in nature. It is sometimes called a structure or a record or by a language-specific keyword used to define one such as struct.
