Structured Chart

 Structured Chart
This is almost a tree with a tree root at the top. The whole problem is
broken into smaller modules. This chart not only shows the way how
they are broken but also the way how the programme is controlled by
parameter passing between higher and lower level modules. There are
several rules to express all these. Now we will show the structured
diagram of result processing in fig 7.1 and then discuss certain rules of
structured chart.
Result processing is done for every student so the every operation will
iterate several times. The direction is denoted by directed arrows. The
rectangular box denotes modules. The diamond with submodule denotes
the conditional branch to another submodule
For example in the above structured diagram roll parameter is passed to
mark finder. The mark finder module gives a Boolean parameter if this is
true then mark found and grade is calculated otherwise absence of the
student in that course is announced.
