What is a flowchart primarily used for in programming?

A flowchart is primarily used in programming as a representation of algorithms and program structure. It visually outlines the sequence of steps or processes required to achieve a specific outcome, making it easier for programmers and developers to understand how different components of the program interact with one another. By using standardized symbols, such as ovals for start and end points, rectangles for processes, and diamonds for decision points, flowcharts allow for a clear and concise illustration of logical flows and decision-making pathways within a program.

This visual representation is particularly useful during the planning phase of development, as it helps identify potential issues, streamline processes, and communicate ideas more effectively among team members. By mapping out the algorithm in this way, programmers can see the entire structure of their code before they start writing it, which can lead to better program design and easier debugging later on.

While the other choices address different aspects of programming and code development—such as user interfaces, documentation for comments, and testing code efficiency—they do not encapsulate the primary function of flowcharts, which is to depict the logic and structure of algorithms.
