                                         Input/Output: It represents reading input or writing output.



                                         Processing: It indicates the processing of the input provided.


                                         Decision: If there is a choice to be made between two options, this
                                         symbol is used. It has two flow lines outwards, representing Yes or

                                         No and True or False.


                                         Flow Line: It is used to show the direction in which the process flows.


                                         Terminal: It represents the start and stop point of the flowchart. A
                                         flowchart always has a start and an end.

                                         Connector: It is used as a connection to show a jump from one point
                                         in the flowchart to another. Connectors are usually labelled in pairs

                                         to show matching jump points.


            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.
