    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 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, the coding becomes easy for the programmer.

                                DRAWING A FLOWCHART

                      Let us now learn how to draw a flowchart.
