                                   Decision          It indicates a question or branch in the process flow. It is used

                     Diamond                         when there are 2 options (Yes/No).

                                   Flow Line         It shows the direction in which the process flows.

                 Rules to Draw Flowcharts                                                            Start

                 You must follow these basic rules while drawing a flowchart:
                    Maintain  the  direction  of  the  flow  from  left  to  right  or  top  to
                                                                                              Read P for Principal
                    bottom.                                                                        r for rate
                    Only one flow line should come out from a process box.                         t for time

                     Only one flow line should enter a decision box, but two flow lines
                    should leave the decision box.
                                                                                             Calculate
                    Ensure that the flowchart has a logical start and end.                   SI = (P * r * t)/100
                 Look at the flowchart to calculate simple interest.

                 Solving Problems using Algorithms and Flowcharts

                 Some examples are given below to solve the problems using algorithms and flowcharts:

                 Example 1: Write an algorithm and draw a flowchart to check weather a given number is even
                 or odd.
                               Algorithm:                             Flowchart:

                 Step 1   Start.
                                                                         Start
                 Step 2   Read Number.

                 Step 3   Check If Number % 2 == 0 Then
                                                                    Read a Number
                          print "Number is even."

                          Else
                                                                           Is
                                                                                      Yes
                          print "Number is odd."                    Number%2==0?             Print Number is even

                 Step 4   End.
                                                                             No

                                                                         Stop


                                                                                     Algorithmic Intelligence  69
