Question 16 of 20
1.0/ 1.0 Points
What can we do with the Circle symbol when drawing the flowchart to represent the algorithm?
A.Use it to represent a decision point in the process. Typically, the statement in the
symbol will require a `yes' or `no' response and branch to different parts of the flowchart
accordingly
B.Use it to represent an event which occurs automatically. Such an event will trigger a
subsequent action, for example `receive telephone call, or describe a new state of affairs.
C.Use it to represent an event which is controlled within the process. Typically this will be
a step or action which is taken. In most flowcharts this will be the most frequently used
symbol
D.Use it to represent a point at which the flowchart connects with another process. The
name or reference for the other process should appear within the symbol
