Which notation is used to depict a control flow?

• A. It is depicted as a dashed line with an open arrowhead or a solid line with an open arrowhead.
• B. It is depicted as a convex pentagon.
• C. It is depicted as a concave pentagon.
• D. It is depicted as a rounded rectangle.

Answer: (A)

Control flow is shown by the directing line that connects steps and indicates the order of execution. An arrowhead on that line signals which step comes next, and using either a dashed or solid line is common in different diagram styles. The key idea is the arrow that guides the sequence from one action to the next. The other shapes—convex pentagon, concave pentagon, rounded rectangle—are symbols for steps or processes themselves, not for how the flow moves between them. So the notation that uses a line with an arrowhead best communicates the path of control through the diagram.
