Difference Between Imperative and Declarative Programming?

Final answer:

The difference between imperative and declarative programming is that imperative programming involves writing detailed instructions for the computer, while declarative programming specifies the desired outcome without detailing the procedure to achieve it.

Step-by-step explanation:

The main difference between imperative and declarative programming lies in how we tell the computer what to do. In imperative programming, we write code that describes in detail the steps that the computer must take to achieve a goal, effectively providing algorithms. A common example of imperative programming is a recipe for baking, which outlines each step required to bake a cake. On the other hand, declarative programming focuses on what the result should be rather than how to achieve it. In this paradigm, we describe the desired outcome, and the computer determines the best way to achieve that outcome. An example of declarative programming is SQL, where you describe the data you want to retrieve from a database without specifying the retrieval process.

Both styles have their uses depending on the task at hand. Declarative programming can be more concise and easier to reason about, while imperative programming can provide more control over the computation process.

In general, when comparing imperative to declarative statements, one might look at the use of periods. For example, the declarative sentence 'The administration canceled classes.' states a fact, while the imperative form directs an action without explicitly stating who is to perform it.
