                      RULES FOR DRAWING A FLOWCHART
                      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 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.
