Which flowchart symbol represents user input or output?

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

Answer: (D)

The flowchart symbol that represents user input or output is the parallelogram. This shape is specifically used to depict processes where data is being entered into or retrieved from a system. In traditional flowcharting, input (like entering data) and output (like displaying results) operations are visually distinguished by the parallelogram, allowing anyone reading the flowchart to quickly understand where user interaction occurs. In contrast, the rectangle is typically used to indicate a process or operation, the diamond symbolizes a decision point where a question is asked, and the oval represents the start or end of the flowchart. This distinction is vital for clear communication of the operations and flow of information within a system.
