Which symbol indicates an input or output operation in a flowchart?

• A. Rectangle
• B. Diamond
• C. Parallelogram
• D. Oval

Answer: (C)

In flowcharts, symbols are chosen to represent the type of action happening. An input or output operation is shown with a parallelogram because it signifies data moving into or out of the process. For example, reading a value from the keyboard or writing a result to the screen uses this shape. Other symbols have distinct roles: a rectangle for a processing step, a diamond for a decision that leads to branches, and an oval for the start or end of the flow. So the parallelogram is the one that conveys input or output.
