Question

Identify different elements of a flow chart and come up with a final flow chart for the following scenario. Also, write the pseudo code. Marks: 20

(Marks Distribution: Identification of elements: 4, flow: 10, use of standard symbols: 6)

The program should take two numbers (num1 and num2) as input from the user

It should check that both are numbers are positive and num1 is less than num2. If that’s not the case, the program displays an error and exits.

It should then display all the multiples of 3 between these two numbers (num1 and num 2)

For example, if the user enters 10 and 30. The program should display 12 15 18 21 24 27 30

Answer 1

The flow chart for the given scenario involves taking two numbers as input, checking their validity, and then displaying multiples of 3 between them.

Step-by-step explanation

The flow chart begins with the user inputting two numbers, num1 and num2. The first step checks whether both numbers are positive and if num1 is less than num2. If either condition is not met, the program displays an error and exits.The next step involves a loop that iterates through the range from num1 to num2. Within this loop, there's a check for multiples of 3 using the modulo operator (%). If a number is divisible by 3
`(i % 3 == 0),\\eq` it is displayed.

For instance, let's consider the user input of 10 and 30. The program checks the conditions (10 is positive, 30 is positive, and 10 < 30), and then it enters the loop. As the loop iterates from 10 to 30, it identifies multiples of 3 and displays them. In this case, the multiples are 12, 15, 18, 21, 24, 27, and 30.

This ensures that the program correctly filters and displays the multiples of 3 within the specified range. The logic is designed to handle different input scenarios, providing an effective and accurate solution to the problem.
