Pseudo Code for Computing the Average of Three Numbers

Objective

To compute the average of three user-provided numbers.

Input

• Three numbers (let's call them num1, num2, and num3).

Processing Steps

1. Read Input: Get the three numbers from the user.
2. Calculate Total: Sum the three numbers.
3. Compute Average: Divide the total by the number of inputs (which is 3).
4. Output Result: Display the calculated average.

Pseudo Code

BEGIN
    DECLARE num1, num2, num3 AS REAL
    DECLARE total AS REAL
    DECLARE average AS REAL

    // Step 1: Read Input
    PRINT "Enter first number:"
    INPUT num1
    PRINT "Enter second number:"
    INPUT num2
    PRINT "Enter third number:"
    INPUT num3

    // Step 2: Calculate Total
    total = num1 + num2 + num3

    // Step 3: Compute Average
    average = total / 3

    // Step 4: Output Result
    PRINT "The average of the three numbers is: ", average
END

Explanation

• Variables Declaration: We define variables to store the three numbers, their total, and the computed average.
• Input/Output: The program prompts the user for input and provides output clearly.
• Arithmetic Calculation: The average is calculated by dividing the sum of the three numbers by three, ensuring accurate and straightforward calculations.

This structure emphasizes clarity and simplicity, making it easy for anyone to understand the logic behind computing an average.
