P. 57

    Step 6:  Print the sum.
                     Step 7:  Subtract number B from the number A.

                     Step 8:  Print the difference.
                     Step 9:  Stop.

                     B.  Algorithm to find the smaller of two numbers A and B.
                     Step 1:  Start.

                     Step 2:  Read two numbers and store them in A and B.

                     Step 3:  Compare number A and B. If A is less than B, print "A is smaller" and go to Step 5.
                     Step 4:  Compare number A and B. If B is less than A, print "B is smaller" and go to Step 5.

                     Step 5:  Stop.

                            DEFINING FLOWCHARTS

                     A flowchart is a type of graphical diagram that represents an algorithm. It is a set of instructions that
                     can be followed to perform a specific task, workflow or process. This diagrammatic representation

                     illustrates  a  solution  model  to  a  given  problem. Flowcharts are  used  in  analysing,  designing,
                     documenting or managing a process or program in various fields.
                     Flowcharts show the sequence of instructions in a single program. They play a vital role in the field
                     of programming. These are helpful in understanding the logic of complicated and lengthy problems.

                     Once a flowchart is drawn, it becomes easy to write the program in any high-level language. Often
                     we see that flowcharts are helpful in explaining the program to others. Hence, it is correct to say that
                     a flowchart is essential for the better understanding of a complex program.

                          Symbols used in Flowcharts

                     Different symbols are used to draw different types of flowcharts. Let us discuss them.

                        Symbol             Name                                    Description

                                                          It is used to show the start and stop points of the flowchart. It
                                    (Start/Stop)
                                                          usually contains the words 'Start' or 'Stop'.

                                                          It shows a process or action step. This is the most common
                                    Process
                                                          symbol used in flowcharts.

                                                          It indicates a question or branch in the process flow. It is used
                                    Decision
                                                          when there are two options (Yes/No).

                                                          It represents material or information entering or leaving the
                                    Input/Output
                                                          system, i.e., input and output.

                                                                                              Flowcharts and Algorithms  55
