Pseudo Code for Calculating Average of Numbers

Objective

1. Input 10 numbers.
2. Calculate the average of all input numbers.
3. Calculate the average of even numbers from the input.
4. Output both averages.

Pseudo Code

BEGIN
    // Initialize variables
    total_sum <- 0
    even_sum <- 0
    even_count <- 0

    // Input 10 numbers
    FOR i FROM 1 TO 10 DO
        PRINT "Enter number", i, ":"
        num <- READ_USER_INPUT()
        
        // Update total sum
        total_sum <- total_sum + num

        // Check if the number is even
        IF num MOD 2 = 0 THEN
            even_sum <- even_sum + num
            even_count <- even_count + 1
        END IF
    END FOR

    // Calculate average of all numbers
    average_total <- total_sum / 10

    // Calculate average of even numbers if any even numbers were found
    IF even_count > 0 THEN
        average_even <- even_sum / even_count
    ELSE
        average_even <- 0 // Handle case where no even numbers are present
    END IF

    // Output the results
    PRINT "Average of all numbers:", average_total
    PRINT "Average of even numbers:", average_even
END

Explanation

• Initialization: We start by initializing the sum variables and counters needed to keep track of the total and the even numbers.
• Input Loop: A loop that iterates 10 times to read user input for numbers.
• Sum Calculation: Both the total sum and the even sum are updated based on user input. The even count is also incremented when an even number is encountered.
• Average Calculation: After input, the averages are calculated based on the sums and respective counts.
• Output: Finally, the averages are displayed to the user.

This pseudo code structure emphasizes clarity in the flow of logic, making it easier to understand and implement in any programming language.
