MAKING A CUP OF TEA
                                                                       CALCULATE THE SUM OF TWO NUMBERS
                 Step  1     Start
                                                                       Step  1     Start.
                 Step  2       Collect Kettle, Teabags, water, milk,
                             sugar and cup                             Step  2       Read  two  numbers and  store
                                                                                   them in A and B.
                 Step  3     Boil the water in the kettle.
                                                                       Step  3     Add two numbers A and B.
                 Step  4     Pour the boiling water into the cup.
                                                                       Step  4     Print the sum.
                 Step  5       Add milk, sugar and put a teabag in
                             a cup.                                    Step  5     Stop.

                 Step  6     Stir the tea and the tea is ready.

                 Step  7     Stop.

                 CALCULATING THE AREA OF A CIRCLE
                 Step  1     Start.

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

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