In a flowchart, which shape represents input or output operations?

• A. Process
• B. Input/Output
• C. Decision
• D. Flow line

Answer: (B)

In flowcharts, the shape used for input and output operations is the parallelogram. Its slanted sides signal data entering or leaving the system, which fits actions like reading input from a user or displaying results. This is different from a rectangle, which represents a processing step, and a diamond, which shows a decision that splits the flow. So when you see a parallelogram, you know the box is dealing with input or output rather than calculating or deciding. For example, commands like "read name" or "print receipt" would be placed in this shape.
