In computer programming, a variable is an abstract storage location paired with an associated symbolic name, which contains some known or unknown quantity...

useful for teaching programming. Since English is the foundation language or lingua franca of most computer programming languages, variables that originate...

symbol. In computer programming, the term free variable refers to variables used in a function that are neither local variables nor parameters of that...

Local variables are fundamental to procedural programming, and more generally modular programming: variables of local scope are used to avoid issues with...

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

In computer programming, the scope of a name binding (an association of a name to an entity, such as a variable) is the part of a program where the name...

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

different from other variables and identifiers used in programming codes. Nevertheless, note that case sensitivity in environment variable names differs between...

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

constraint on the slack variable is also added.: 131  Slack variables are used in particular in linear programming. As with the other variables in the augmented...

In computer programming, a variable-length array (VLA), also called variable-sized or runtime-sized, is an array data structure whose length is determined...

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

In class-based, object-oriented programming, a class variable is a variable defined in a class of which a single copy exists, regardless of how many instances...

if functions with free variables are first-class, then returning one creates a closure. This includes functional programming languages such as Lisp and...

such, it is a programming error and a common source of bugs in software. A common assumption made by novice programmers is that all variables are set to...

In the C programming language, and its predecessor B, an external variable is a variable defined outside any function block. On the other hand, a local...

research. In constraint programming, users declaratively state the constraints on the feasible solutions for a set of decision variables. Constraints differ...

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