Workshop: Algorithm and Flowchart

For each question in this workshop, you must complete two things:

1. Write the pseudocode
2. Draw the flowchart using either
   • Option 1: Draw.io (recommended) → export image → upload to your repository → link it in this file
   • Option 2 (optional): Write a Mermaid flowchart directly in Markdown
   • Option 3 (optional): Any other valid method

👉 IMPORTANT: At the bottom of each question, add the following sections:

✔ Pseudocode

✔ Flowchart

---

1. Check Even or Odd Number

Design an algorithm and flowchart that take a number as input and determine whether it is even or odd.

✔ Pseudocode

START
    INPUT number
    IF number % 2 == 0 THEN
        PRINT Even
    ELSE
        PRINT Odd
    ENDIF
END

✔ Flowchart

flowchart TD
    A([Start]) --> I[/Get input N/]
    I --> B{N % 2 == 0 ?}
    B -->|Yes| C[/Print Even/]
    B -->|No| D[/Print Odd/]
    C --> E([End])
    D --> E([End])

2. Calculate Total and Average Marks

Write the algorithm and draw the flowchart for a program that inputs marks for 3 subjects, calculates the total and average, and displays both.

---

3. Display Multiplication Table

Create an algorithm and flowchart that input a number and display its multiplication table from 1 to 10 using a loop.

---

4. Positive, Negative, or Zero Check

Write the algorithm and flowchart to input a number and display whether it is positive, negative, or zero.

---

5. Simple Interest Calculator

Create an algorithm and flowchart for a program that calculates simple interest using the formula:

SI = (P × R × T) / 100

• P = Principal → original amount of money
• R = Rate of Interest → percentage per year
• T = Time → number of years

6. Average Temperature Calculation

Write the algorithm and draw the flowchart for a program that takes the temperature of 7 days, finds the average temperature, and displays it.

---

7. Calculate Area of a Rectangle

Create an algorithm and flowchart to input length and width, calculate the area (Area = Length × Width), and display the result.

---

8. Determine Pass or Fail

Write the algorithm and draw the flowchart for a program that takes a student's average marks and displays "Pass" if average ≥ 50, otherwise "Fail".

---

9. Calculate Factorial of a Number

Write the algorithm and draw the flowchart that input a number and calculate its factorial using a loop.

10. Calculate Discount on Purchase

Write the algorithm and draw the flowchart for a program that inputs the purchase amount and gives a 10% discount if the amount is greater than 1000.
