An '''expression''' in a [[programming language]] it is when a variable is not being declared. Combinecombination of explicit, over use statements enhance if/else/ || loop statements. Boolean exponents should be the focus thus providing the ""expression"" compute the javac/switch value and compile to reach an overall statement, value/expression, thus [[value (computer science)|value]]s, [[Constant (programming)|constants]], [[variable (programming)|variable]]s, [[operator (programming)|operator]]s, and [[function (programming)|function]]s that are interpreted according to the particular [[Order of operations|rules of precedence]] and of association for a particular programming language, which computes and then produces (returns, in a [[state (computer science)|stateful]] environment) another value. This process, like for [[mathematical expression]]s, is called evaluation. The value can be of various [[Data type|type]]s, such as numerical, string, and logical.
For example, 2+3 is an arithmetic and programming expression which evaluates to 5. A variable is an expression because it denotes a value in memory, so y+6 is an expression. An example of a relational expression is 4≠4, which evaluates to false.<ref>[https://developer.mozilla.org/en/Core_JavaScript_1.5_Guide/Expressions Javascript expressions, Mozilla] Accessed July 6, 2009</ref><ref>[https://www.cs.drexel.edu/~rweaver/COURSES/ISTC-2/TOPICS/expr.html Programming in C] Accessed July 6, 2009</ref>
