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
                  print "Number is odd."                                          Yes
                                                               Number%2==0?             Print Number is even
        Step 4:  End.

                                                                        No

                                                             Print Number is odd



                                                                     Stop


        Example 2: Write an algorithm and draw a flowchart to find the smallest in two numbers A and B.


                         Algorithm:                               Flowchart:
        Step 1:  Start.                                               Start

        Step 2:   Read two numbers and store them

                  in A and B.
                                                                 Read A and B
        Step 3:   Compare number  A  and  B.  If  A  is
                  less than B, then

                   print "A is smallest"                               if         Yes
                                                                     A < B                Print A is smallest
                  Else

                  print "B is smallest"                                  No

        Step 4:  End.
                                                               Print B is smallest



                                                                      Stop
