Question
What are the standard flowchart symbols?
Answer
Rounded box for Start/End, slanted box for Input/Output, rectangle for Process, diamond for Decision with two labelled exits, arrow for Flowline, and a small circle for Connector.
Question
How is a loop shown on a flowchart?
Answer
There is no loop symbol. A loop is a decision diamond with a flowline going back up to it — follow the arrows and the loop is obvious.
Question
How do you trace a flowchart reliably?
Answer
Draw the table first with one column per variable plus output; write a new row for every change; write the comparison out in full at every diamond; and add to the output column only when an output box is reached.
Question
What is the commonest tracing error?
Answer
The boundary case. When the test is 'count at most N', the loop still runs when the two values are equal — one more time than most people expect.
Question
How many exits does a decision symbol have?
Answer
Exactly two, labelled Yes and No. A diamond drawn with one exit or with three is drawn incorrectly.
