An exclamative is a sentence type in English that typically expresses a feeling or emotion, but does not use one of the other structures. It often has the form as in the examples below of [WH + Complement + Subject + Verb], but can be minor sentences (i.e. without a verb) such as [WH + Complement] How wonderful!.
Imperative sentences sometimes use different syntax than declarative or other types of clauses. There may also be differences of syntax between affirmative and negative imperative sentences. In some cases the imperative form of the verb is itself different when negated.
In many circumstances, using the imperative mood may sound blunt or even rude, so it is often used with care. Example: "Pat, do your homework now". An imperative is used for telling someone to do something without argument. Many languages, including English, use the bare verb stem to form the imperative (such as "go", "run", "do").

Declarative and interrogative clauses may be independent or dependent, but imperative clauses are only independent.
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.
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.
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.
