- Variable (high-level programming) - Wikipedia
In high-level programming, a variable is an abstract storage or indirection location paired with an associated symbolic name, which contains some known or unknown quantity of data or object referred to as a value; or in simpler terms, a variable is a named container for a particular set of bits or type of data (like integer, float, string, etc
- Type variable - Wikipedia
In type theory and programming languages, a type variable is a mathematical variable ranging over types Even in programming languages that allow mutable variables, a type variable remains an abstraction, in the sense that it does not correspond to some memory locations
- Value type and reference type - Wikipedia
Value type and reference type In certain computer programming languages, data types are classified as either value types or reference types, where reference types are always implicitly accessed via references, whereas value type variables directly contain the values themselves [1][2]
- C data types - Wikipedia
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 Data types also determine the types of operations or methods of processing of data elements The C language provides basic arithmetic types, such as integer and real number types
- Data type - Wikipedia
The standard type hierarchy of Python 3 In computer science and computer programming, a data type (or simply type) is a collection or grouping of data values, usually specified by a set of possible values, a set of allowed operations on these values, and or a representation of these values as machine types [1] A data type specification in a program constrains the possible values that an
- Free variables and bound variables - Wikipedia
Free variables and bound variables In mathematics, and in other disciplines involving formal languages, including mathematical logic and computer science, a variable may be said to be either free or bound Some older books use the terms real variable and apparent variable for free variable and bound variable, respectively
- Primitive data type - Wikipedia
Primitive data type In computer science, primitive data types are sets of basic data types from which all other data types are constructed [1] Specifically it often refers to the limited set of data representations in use by a particular processor, which all compiled programs must use
- Array (data type) - Wikipedia
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 and matrix, array types with one and two indices are
