Symbols Used in Flowcharts

              Different symbols are used to draw different types of flowcharts.

                   Symbol              Name                                     Description


                                                       It is used to show the start and stop points of the flowchart.
                                Start/Stop
                     Oval                              It usually contains the words 'Start' or 'Stop'.


                                Process                It shows a process or action step.
                  Rectangle


                                                       It represents information entering or leaving the system, i.e.,
                                Input/Output
                Parallelogram                          input and output.

                                                       It indicates a question or branch in the process flow. It is used
                                Decision               when there are 2 options (Yes/No).

                  Diamond

                    Arrow       Flow Line              It shows the direction in which the process flows.

              Rules to Draw Flowcharts


              You must follow these basic rules while drawing a flowchart:
                  Maintain the direction of the flow from left to right or top to bottom.

                  Only one flow line should come out from a process box.
                  Only one flow line should enter a decision box, but two flow lines should leave the decision box.
                  Ensure that the flowchart has a logical start and end.

              Look at the flowchart to calculate simple interest.

                                                                Start



                                                         Read P for Principal

                                                                  r for rate
                                                                  t for time



                                                          Calculate
                                                          SI = (P * r * t)/100


                                                               Print SI



                                                                Stop
