    Symbols Used in Flowcharts

                  Different symbols are used to draw different types of flowcharts.

                       Symbol              Name                                     Description

                  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 stop.

                  Look at the flowchart to calculate simple interest.

                                                                    Start

                                                             Read P for Principal

                                                                      t for time

                                                                   Print SI
