                 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 whether 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
                           print "Number is odd."                                           Yes
                                                                       Number%2==0?             Print Number is even
                 Step 4:  Stop.
                                                                                No


                                                                     Print Number is odd




                                                                             Stop
