Question

Quizplus · Accepted Answer

A line with a diamond on one end is used to represent a condition, where the module on the non-diamond end executes only if the condition is satisfied. An arrow with a filled circle represents an iteration or loop, while an arrow with an empty circle represents a module that calls another module but does not wait for it to complete. A line with a diamond on both ends is not used in structure charts.
