What is described as pair programming?

Pair programming is a collaborative software development practice where two developers work together at one workstation to write code. This approach allows for immediate feedback and continuous code review, as one developer takes the role of the "driver," who is responsible for typing and writing the code, while the other, known as the "observer" or "navigator," focuses on examining the code being written, considering the overall solution, and suggesting improvements.

This method enhances collaboration, encourages knowledge sharing, and can lead to higher quality code because the immediate interpersonal interaction facilitates quick problem-solving and creative brainstorming. It embodies a strong aspect of Agile methodologies, where teamwork and responsiveness to change are prioritized.

Options that describe developers working independently or merely reviewing code do not capture the essence of the immediate, collaborative nature of pair programming. The concept of one developer simply leading while the other follows also deviates from the mutual engagement that is characteristic of true pair programming, where both participants actively contribute to the coding process. Thus, the correct choice reflects the fundamental principles and practice of pair programming accurately.
