Difficulty: Easy
Correct Answer: Input/Output
Explanation:
Introduction / Context:
Flowcharts use a small set of standardized symbols to describe program logic and system procedures. Correct symbol usage improves communication between analysts, designers, and developers.
Given Data / Assumptions:
Concept / Approach:
The Input/Output symbol (a parallelogram) represents data entry and display operations. Although it covers both input and output, the same symbol is used when a step specifically gets user information.
Step-by-Step Solution:
Verification / Alternative check:
Review any ANSI/ISO flowchart legend: input and output are combined in the same symbol.
Why Other Options Are Wrong:
Process is not specific to I/O, decision symbols handle branching, and start/stop delimit the routine; none represent user input explicitly.
Common Pitfalls:
Using a process rectangle for data entry steps reduces clarity; always apply the I/O parallelogram for input or output activities.
Final Answer:
Input/Output
