B. Structural elements might come separately
C. Indenting is used to show structure in the algorithm
D. The names of subprograms are underlined
8. What can we do with the Circle symbol when drawing the flowchart to represent the
algorithm?
A. 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.
B. 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
C. 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
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

formal parameters
