                                                       labelled in pairs to show matching jump points.



                       Rules to Draw Flowcharts

                  You must follow these basic rules while drawing a flowchart:
                     The flowchart should be clear, neat and easy to follow.

                     Maintain the direction of the flow from left to right or top to bottom.
                     Only one flow line should come out from a process symbol.

                      Ensure that only one flow line should enter a decision symbol, but two flow lines should leave the
                    decision symbol.
                                                                                      Example 2: Flowchart to add
                     Ensure that the flowchart has a logical start and end.
                                                                                      first 100 natural numbers.
                       Advantages of Flowcharts
                                                                                                    Start
                  Flowcharts provide following advantages:

                     It provides a better understanding of a problem.
                                                                                                   Sum = 0
                     It facilitates a programmer to analyse the problem in detail.

                  Let us understand how some simple flowcharts are made.
                  Example 1:  Flowchart to calculate simple interest.                                N = 0
