                      LAB ACTIVITY                                                                     Inter-Disciplinary


                       Visit your computer lab and perform the following actions:
                       ▶  Draw the flow chart for the following:

                          (a)  to calculate the factorial of a number.

                          (b)  to check if a given number is odd or even.
                       ▶  Write an algorithm for the following:

                          (a)  to determine the largest number among the three numbers.
                          (b)  to calculate the simple interest.

                  FUN ACTIVITY

                   Take a chart paper and draw all the symbols used while creating a flowchart. Also, mention the
                   names and the use of each symbol.

                                                                                                             []
                                                                          </>
                     Following is an algorithm to accept the age of a person and check whether he/she is eligible to
                     vote or not. A person can only vote if he/she is 18 years old or more. Number the steps of the
                     algorithm in the correct order.
                          Accept the age of the person.                   Stop.

                          If age is greater than or equal to 18, then display, ‘You are eligible to vote’.
                          Start.

                          If age is less than 18, then display, ‘You are not eligible to vote’.




                   FOR THE TEACHER
                  1.   Discuss with the students about the development of machine/assembly languages, then 3rd generation procedural
                     languages like C to object-oriented languages like Java.
                  2.   Assign the task of making algorithms and flowcharts based on real-life situations to help students understand the
                     concepts easily.
