The variable name is the usual way to reference the stored value; this separation of name and content allows the name to be used independently of the exact information it represents. The identifier in computer source code can be bound to a value during run time, and the value of the variable may thus change during the course of program execution.\r\n\r\n<h3>See Also</h3>\r\n<ul>\r\n<li>Non-local variable</li>\r\n<li>Variable interpolation</li>\r\n</ul>\r\n', 'k8805', '2015-05-14 10:04:00');INSERT INTO `topic` (`id`, `title`, `description`, `author`, `created`) VALUES(3, 'Opeartor', '<h2>Operator</h2>\r\n<h3>Description</h3>\r\n<p>Programming languages typically support a set of operators: constructs which behave generally like functions, but which differ syntactically or semantically from usual functions</p>\r\n<p>Common simple examples include arithmetic (addition with +, comparison with >) and logical operations (such as AND or &&). </p>\r\n', 'egoing', '2015-06-18 05:00:00');INSERT INTO `topic` (`id`, `title`, `description`, `author`, `created`) VALUES(4, 'Conditional', '<h3>Description</h3>\r\n<p>In computer science, conditional statements, conditional expressions and conditional constructs are features of a programming language which perform different computations or actions depending on whether a programmer-specified boolean condition evaluates to true or false.
