In computer programming, a parameter, a.k.a. formal argument, is a variable that represents an argument, a.k.a. actual argument, a.k.a. actual parameter...

In computer programming, a variable is said to be volatile if its value can be read or modified asynchronously by something other than the current thread...

A metasyntactic variable is a specific word or set of words identified as a placeholder in computer science and specifically computer programming. These...

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...

class variable is a variable defined in a class of which a single copy exists, regardless of how many instances of the class exist. A class variable is not...

In computer programming, a global variable is a variable with global scope, meaning that it is visible (hence accessible) throughout the program, unless...

In computer programming, a static variable is a variable that has been allocated "statically", meaning that its lifetime (or "extent") is the entire run...

stack space for variables, and the collection of variables allocated for a subroutine is known as a stack frame. While the computer will set aside the...

In computer programming, string interpolation (or variable interpolation, variable substitution, or variable expansion) is the process of evaluating a...

object-oriented programming, an instance variable is a variable defined in a class (i.e., a member variable), for which each instantiated object of the...

This glossary of computer science is a list of definitions of terms and concepts used in computer science, its sub-disciplines, and related fields, including...

In computer science, a local variable is a variable that is given local scope. A local variable reference in the function or block in which it is declared...

B, an external variable is a variable defined outside any function block. On the other hand, a local (automatic) variable is a variable defined inside...

theory, a non-local variable is a variable that is not defined in the local scope. While the term can refer to global variables, it is primarily used...

An undefined variable in the source code of a computer program is a variable that is accessed in the code but has not been declared by that code. In some...

In computer programming, an automatic variable is a local variable which is allocated and deallocated automatically when program flow enters and leaves...

In software engineering and computer science, abstraction is the process of generalizing concrete details, such as attributes, away from the study of objects...

In computer programming, variable shadowing occurs when a variable declared within a certain scope (decision block, method, or inner class) has the same...

In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. The latter may allow...

In computer programming, a sigil (/ˈsɪdʒəl/) is a symbol affixed to a variable name, showing the variable's datatype or scope, usually a prefix, as in...

In object-oriented programming, a member variable (sometimes called a member field) is a variable that is associated with a specific object, and accessible...

In computer science, an operation, function or expression is said to have a side effect if it has any observable effect other than its primary effect of...

In computer programming, a temporary variable is a variable with short lifetime, usually to hold data that will soon be discarded, or before it can be...

In computer science, primitive data types are a set of basic data types from which all other data types are constructed. Specifically it often refers to...

introduced by C. J. Date and Hugh Darwen as an abbreviation for relation variable in their 1995 paper The Third Manifesto, to avoid the confusion sometimes...

In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or...
