  2. Statement (computer science) - Wikipedia

    en.wikipedia.org/wiki/Statement_(computer_science)

    Expressions always evaluate to a value, which statements do not. However, expressions are often used as part of a larger statement. In most programming languages, a statement can consist of little more than an expression, usually by following the expression with a statement terminator (semicolon).

  3. Comparison of programming languages (syntax) - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_programming...

    A language that supports the statement construct typically has rules for one or more of the following aspects: Statement terminator – marks the end of a statement; Statement separator – demarcates the boundary between two statements; need needed for the last statement; Line continuation – escapes a newline to continue a statement on the ...

  4. Expression-oriented programming language - Wikipedia

    en.wikipedia.org/wiki/Expression-oriented...

    An expression-oriented programming language is a programming language in which every (or nearly every) construction is an expression and thus yields a value. [1] The typical exceptions are macro definitions, preprocessor commands, and declarations , which expression-oriented languages often treat as statements .

  5. Expression (computer science) - Wikipedia

    en.wikipedia.org/wiki/Expression_(computer_science)

    In computer science, an expression is a syntactic entity in a programming language that may be evaluated to determine its value. [1] It is a combination of one or more constants, variables, functions, and operators that the programming language interprets (according to its particular rules of precedence and of association) and computes to produce ("to return", in a stateful environment ...

  7. eval - Wikipedia

    en.wikipedia.org/wiki/Eval

    Visual Basic for Applications (VBA), the programming language of Microsoft Office, is a virtual machine language where the runtime environment compiles and runs p-code. Its flavor of Eval supports only expression evaluation, where the expression may include user-defined functions and objects (but not user-defined variable names).

  8. Lazy evaluation - Wikipedia

    en.wikipedia.org/wiki/Lazy_evaluation

    When using delayed evaluation, an expression is not evaluated as soon as it gets bound to a variable, but when the evaluator is forced to produce the expression's value. That is, a statement such as x = expression; (i.e. the assignment of the result of an expression to a variable) clearly calls for the expression to be evaluated and the result ...

  9. Syntax (programming languages) - Wikipedia

    en.wikipedia.org/wiki/Syntax_(programming_languages)

    In computer science, the syntax of a computer language is the rules that define the combinations of symbols that are considered to be correctly structured statements or expressions in that language. This applies both to programming languages, where the document represents source code, and to markup languages, where the document represents data.
