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

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

                 B. Algorithm to find the smallest in 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 smallest" and go to Step 5.

                 Step 4:  Compare number A and B. If B is less than A, print "B is smallest" 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 must 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.
