In programming, what does 'iterative' typically refer to?

The term 'iterative' in programming refers to a repetitive process of development. This concept is essential in various aspects of software development, particularly in methodologies like Agile and Scrum, where iterations are used to gradually refine and improve a product based on feedback. In an iterative process, features or components are developed, tested, and reviewed in cycles, allowing for continuous improvement and adaptation.

This approach enables teams to identify issues early in the development cycle, respond to changing requirements, and progressively deliver a more polished final product. By focusing on iterations, developers can prioritize features based on user feedback, ensuring that the end result aligns more closely with user needs.

The other options present distinct concepts that do not capture the essence of 'iterative' in the context of programming. A final testing stage, for instance, implies a one-time evaluation rather than a cyclical process. Similarly, while a type of algorithm may have iterative components, it does not encompass the broader, repetitive development process that the term 'iterative' embodies. An array of functions refers to a data structure used to store multiple functions, which is a different area of programming entirely.
