<p>Created page with "In <a href="/index.php/Computer_science" title="Computer science">computer science</a>, a '''local variable''' is a <a href="/index.php?title=Variable_(programming)&action=edit&redlink=1" class="new" title="Variable (programming) (page does not exist)">variable</a> that is given <a href="/index.php?title=Local_scope&action=edit&redlink=1" class="new" title="Local scope (page does not exist)">local scope</a>. == Description == Local variable references in the fu..."</p>
<p><b>New page</b></p><div>In [[computer science]], a '''local variable''' is a [[Variable (programming)|variable]] that is given [[local scope]].<br />
<br />
== Description ==<br />
<br />
Local variable references in the function or block in which it is declared override the same variable name in the larger scope.<br />
<br />
In [[Programming language|programming languages]] with only two levels of visibility, local variables are contrasted with global variables.<br />
<br />
On the other hand, many ALGOL-derived languages allow any number of nested levels of visibility, with private variables, functions, constants and types hidden within them, either by nested blocks or nested functions.<br />
<br />
Local variables are fundamental to procedural programming, and more generally modular programming: variables of local scope are used to avoid issues with side-effects that can occur with global variables.<br />
