                      Visit your computer lab and perform the following actions:

                      ▶  Draw the flowchart:
                         (a)  To calculate the factorial of a number

                         (b)  To check if a given number is odd or even

                      ▶  Write an algorithm:
                         (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.
                               Stop.
                               Accept the age of the person.
                               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 class  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 class understand the concepts
                          easily.
