This
flowchart
has
three
decision
diamonds.
In
the first,
the
Computer
determines
if an
answer
is
correct.
In the
second,
the
Computer
determines
if
all the
questions
in a
single
student's
paper
have been
graded.
The third
one
terminates
execution
when
all the
tests
have
been graded.
EXERCISE
23-1
:
Using the
flowchart
as a
guide, write
a
program
that grades a test
having
five questions
.
For more
complicated
problems,
you
may want to
subdivide the
flochart
into
larger
modules,
A
master
flowchart
will
then
show
the
relationship
between the flowcharts of indi-
vidual
programs.
