MAKING A CUP OF TEA                                 CALCULATE THE SUM OF TWO NUMBERS

             Step  1   Start.                                    Step  1   Start.
             Step  2   Boil the water in the kettle.             Step  2    Read two numbers and store them

             Step  3   Pour the boiling water into the cup.                in A and B.

             Step  4    Add milk, sugar and put a teabag in      Step  3   Add two numbers A and B.
                       a cup.                                    Step  4   Print the sum.

             Step  5   Stir the tea and the tea is ready.        Step  5   Stop.
             Step  6   Stop.


            CALCULATING THE AREA OF A CIRCLE

            Step  1   Start.

            Step  2    Read the radius of the circle and store it in r. (where, r is the length from the centre of
                      the circle to the edge of the circle.)

            Step  3   Calculate the area of the circle. (Where, Area = π × r (3.14 × radius × radius))
                                                                           2
            Step  4   Print the area.

            Step  5   Stop.




                       FLOWCHART

            A flowchart is the graphical representation of a process and the logic (which is also called an
            algorithm) used in it. Flowcharts are used in analysing, designing, documenting or managing a

            process or program in various fields.

            SYMBOLS USED IN FLOWCHARTS

            A flowchart uses specific geometrical shapes and directional arrows to draw a flow chart for a
            particular task. A set of geometrical boxes represents the steps involved in the solution process.
            Each  box  represents  a  specific  function,  activity and  process.  Directional  arrows are  used  to
            connect the boxes to show the flow of the solution.
