Declarative programming is a non-imperative style of programming in which programs describe their desired results without explicitly listing commands or steps that must be performed. Functional and logic programming languages are characterized by a declarative programming style.
The declarative sentence is the most common kind of sentence in language, in most situations, and in a way can be considered the default function of a sentence. What this means essentially is that when a language modifies a sentence in order to form a question or give a command, the base form will always be the declarative.
Higher-level imperative languages use variables and more complex statements, but still follow the same paradigm. Recipes and process checklists, while not computer programs, are also familiar concepts that are similar in style to imperative programming; each step is an instruction, and the physical world holds the state. Since the basic ideas ...
In computer programming, a statement is a syntactic unit of an imperative programming language that expresses some action to be carried out. [1] A program written in such a language is formed by a sequence of one or more statements. A statement may have internal components (e.g. expressions).
Declarative programming stands in contrast to imperative programming via imperative programming languages, where control flow is specified by serial orders (imperatives). (Pure) functional and logic-based programming languages are also declarative, and constitute the major subcategories of the declarative category. This section lists additional ...
For example, the clause Jo did it has the subject noun phrase Jo followed by the head VP did it. Declarative clauses are associated with the speech act of making a statement. [12]: 127 The following diagram shows the syntactic structure of the clause this is a tree.
An imperative, in contrast, generally applies to the listener. When a language is said to have a jussive, the jussive forms are different from the imperative ones, but may be the same as the forms called "subjunctive" in that language. Latin and Hindi are examples of where the jussive is simply about certain specific uses of the subjunctive.
In the latter case, a (declarative) sentence is just one way of expressing an underlying statement. A statement is what a sentence means, it is the notion or idea that a sentence expresses, i.e., what it represents. For example, it could be said that "2 + 2 = 4" and "two plus two equals four" are two different sentences expressing the same ...
