    Ensure that only one flow line should enter a decision symbol, but two flow lines should leave the
                       decision box.
                       Ensure that the flowchart has a logical start and end.

                     ADVANTAGES OF A FLOWCHART

                     Flowcharts provide the following advantages:

                       Programmers can analyse the problem in detail.
                       Programmers can easily understand the logic.
                       Ideas and solutions can be communicated easily and clearly.

                       Once  the  flowchart  is  prepared,  it  provides  a  clear  blueprint  of  the  coding  process  for  the
                       programmer.

                               DRAWING A FLOWCHART

                     Let us now learn how to draw a flowchart.

                             water, milk, sugar and cup

                              Boil the water in the kettle                                  Calculate
                                                                                         Area = 3.14 × r × r

                         Pour the boiling water into the cup

                                                                                            Print Area
                              Add milk, sugar and put a
                                  teabag in the cup
                                                                                               Stop

                                     Stir the tea

                                    Tea is ready

                                         Stop

                     FINDING THE SMALLER NUMBER BETWEEN TWO NUMBERS

                     There comes a situation where we need to make a decision based on certain conditions.

                                                                                     Algorithm, Flowchart and Mind Maps  67
