In computer programming, a parameter or a formal argument is a special kind of variable used in a subroutine to refer to one of the pieces of data provided...

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

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...

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...

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

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

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

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

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

including mathematical logic and computer science, a variable may be said to be either free or bound. A free variable is a notation (symbol) that specifies...

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

reserved and unused in C++17. It suggests that the compiler stores a declared variable in a CPU register (or some other faster location) instead of in random-access...

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

environment variable is a user-definable value that can affect the way running processes will behave on a computer. Environment variables are part 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...

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...
