In a flowchart, what does a flow line show?

• A. Data input
• B. Flow of control
• C. Loop
• D. A terminator

Answer: (B)

The flow line shows the flow of control—the path that the process follows from one step to the next. Arrows connect the different symbols to indicate the order of execution, guiding what happens after each action or decision. When you reach a decision, the arrows show the possible routes based on conditions, and they may rejoin later to continue the process. It’s not the data input/output symbol, nor the start/end terminator, and any looping is just an arrow returning to an earlier step, creating repetition.
