A local variable reference in the function or block in which it is declared overrides the same variable name in the larger scope An example is the errno used by many functions of the c library In programming languages with only two levels of visibility, local variables are contrasted with global variables

The variable named x is a parameter because it is given a value when the function is called
The integer 5 is the argument which gives x its value
In most languages, function parameters have local scope This specific variable named x can only be referred to within the add_two function (though of course other functions can also have variables called x). Automatic variable in computer programming, an automatic variable is a local variable which is allocated and deallocated automatically when program flow enters and leaves the variable's scope The scope is the lexical context, particularly the function or block in which a variable is defined.
Assigning to a variable of reference type simply copies the reference, whereas assigning to a variable of value type copies the value This applies to all kinds of variables, including local variables, fields of objects, and array elements. 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.
These models attempt to account for the probabilistic features of quantum mechanics via the mechanism of underlying but inaccessible variables, with the additional requirement that distant events be statistically independent
In computer science, local search is a heuristic method for solving computationally hard optimization problems Local search can be used on problems that can be formulated as finding a solution that maximizes a criterion among a number of candidate solutions. While the use of global variables is generally discouraged in modern programming, some older operating systems such as unix were originally designed for uniprocessor hardware and often use global variables to store important values
