What is the main purpose of a flow chart?

• A. To describe visual UI elements
• B. To display code snippets
• C. To list assets
• D. To show the steps and decisions of an algorithm

Answer: (D)

Flow charts are diagrams that map out how a process proceeds from start to finish. They show each step as a box and use decision points (often diamonds) with arrows indicating which path to take next based on yes/no or other outcomes. This makes the logical flow of an algorithm visible: the sequence of operations and the branching decisions that determine which path is followed. That’s why the main purpose is to show the steps and decisions of an algorithm. It helps you plan and discuss the logic before coding, and makes it easier to spot missing steps, unnecessary branches, or potential errors. It isn’t about describing visual UI elements, displaying code snippets, or listing assets—those are different kinds of documentation. By emphasizing the steps to perform and the decisions that steer the process, a flow chart provides a clear, communicative map of how the algorithm operates.
