HOTS (Higher Order Thinking Skills)

Study the image and answer the questions that follow.

Q1. Identify the terminal box(es) and label them as A.

Answer: The terminal boxes are the rounded rectangles at the very top and bottom of the flowchart.

• A: Start (at the top)

• A: Stop (at the bottom)

Q2. Identify the Input/Output box(es) and label them as B.

Answer: These are the parallelograms used for reading data or printing results.

• B: Read Class and Tuition Fee of the student

• B: Print Fee

Q3. Identify the Process box(es) and label them as C.

Answer: These are the rectangles where calculations are performed.

• C: Fee = Tuition Fee + 200

• C: Fee = Tuition Fee + 500

Q4. Is a Decision box being used in the above flowchart? If yes, label it as D.

Answer: Yes, a Decision box is being used. It is the diamond-shaped box in the middle.

• D: Is Class >= 6?

Lab Zone

A. Write an algorithm and draw the flowchart to find the difference of two numbers.

Algorithm:

1. Start

2. Input two numbers (A and B).

3. Calculate the difference: Difference = A - B.

4. Display (Print) the Difference.

5. Stop

Flowchart:

graph TD Start([Start]) --> Input[/Input A, B/] 

Input --> Process[Difference = A - B] Process --> Output[/Print Difference/] Output --> Stop([Stop])

B. Draw a flowchart to check whether the entered number is odd or even.

Algorithm (for context):

1. Start

2. Input a number (N).

3. Check if N is divisible by 2 (Remainder = 0?).

4. If Yes, Display "Number is Even".

5. If No, Display "Number is Odd".

6. Stop

Flowchart:

Start([Start]) --> Input[/Input Number N/] 

Input --> Decision{Is N % 2 == 0?} Decision -- Yes --> Even[/Print Even/] Decision -- No --> Odd[/Print Odd/] Even --> Stop([Stop]) 

 Odd --> Stop
