                                       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.

                                                                                                       Print SI

                                                                                                         Stop
                     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

                                                                      Print Number is odd

                                                                             Stop

                                                                                         Algorithmic Intelligence  69
