									Flowcharts
   A flowchart is a diagrammatic
    representation that illustrates the
    sequence of operations to be performed
    to get the solution of a problem.
   Notation that is often used during the
    design stage of the software life cycle
    for quick and easy understanding of a
    programs flow.

                               Decision
Start          End




                     Process

Input/Output
Start and Ending Blocks
              Start           End




 These blocks are used to start and end a process
 or program.
 These blocks should contain simple labels to
 indicate the process or program.
  Input/Output Block
                        Input/Output




This block can represent either input or output statements.
This block should be labeled with a brief description of the
input or output.
Process Block
                      Process




 The process block represents some operation carried
 out on an element of data. This could be a
 calculation.
 This block should be labeled with a brief description
 of the process being carried out.
Decision Block
                    Decision



                               F




                    T


 The decision block should be a True/False
 choice.
 The label on the block should contain the
 question to the decision that should be made.
How to use these Blocks
   We can imagine using these blocks to
    build up a representation of our
    program.
   Let’s look at our original
    QualifyForLifting program and represent
    it using flowchart notation.
