Which symbol denotes a decision point in a flowchart?

Which symbol denotes a decision point in a flowchart?

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

Answer: (C)

In flowchart notation, the diamond shape marks where a decision is made. A condition is evaluated there and the flow splits into different paths based on the result, such as yes or no, true or false. This branching is what the diamond communicates visually, guiding the process to different steps depending on the outcome. Other shapes have different roles: a rectangle shows a processing step like converting data or performing a calculation; a parallelogram represents input/output, such as reading a value or displaying a result; a circle typically marks the start or end, or serves as a connector between distant parts of the chart. For example, a decision might be “Is the temperature above threshold?” If yes, the flow goes to one path; if no, it goes to another. So the symbol that denotes a decision point is the diamond.
