It is suggested that the reader should go through the logic of this flowchart again and
again until he/she is convinced that the output list provided by the computer will contain
the details of only those female students who have passed in second division. The reader
should also get convinced that finally when the trailer record is detected, the operation
"Write Count" would print out the value of Count that will be equal to the total number of
female students who have passed in second division. This flowchart is an example of a
The flowchart of Figure 11.9 has been reproduced in Figure 11.10 to illustrate the use of
connectors. There are four exit connectors having the label 1 all of which indicate a flow
of control to the flowchart symbol having an entry connector labeled 1. This symbol is
the input symbol in the flowchart. Similarly the exit connector having a label 2 indicates
a flow of control to the entry connector labeled 2. The reader should compare the
flowcharts of Figure 11.9 and Figure 11.10 and should get convinced that both the
flowcharts represent the same logic.
A flowchart may seem simple to prepare, but you will find that much practice is needed
in order to think through a problem in discrete, logical steps, to assume nothing and to
forget nothing. Moreover, not everyone will tackle a problem in exactly the same way
and, in consequence, several different flowcharts could be drafted for the same problem.
It may also be noted that a completed flowchart is not a complete computer program. It is only an aid to programming. For a given problem, it defines the procedure and the logic
involved. From the examples that have been discussed above, we are in a better position
to understand what this "logic" means.
Levels of Flowcharts
There are no set standards on the amount of detail that should be provid...
