Pseudocode for Basic Arithmetic Operations with Looping

Objective

To create an algorithm that repeatedly performs addition, subtraction, multiplication, and division on two user-inputted numbers. The operations will be repeated 10 times using a for loop.

Main Points

• Input: Two numbers from the user
• Operations: Addition, subtraction, multiplication, division
• Repetition: Use of a for loop to repeat the process 10 times

Pseudocode

BEGIN

    // Declare variables
    DECLARE number1
    DECLARE number2
    DECLARE sum
    DECLARE difference
    DECLARE product
    DECLARE quotient

    // Loop 10 times
    FOR i FROM 1 TO 10 DO
        
        // Prompt the user for input
        PRINT "Enter the first number:"
        INPUT number1
        
        PRINT "Enter the second number:"
        INPUT number2

        // Perform arithmetic operations
        sum = number1 + number2
        difference = number1 - number2
        product = number1 * number2

        // Check if second number is not zero to avoid division by zero
        IF number2 != 0 THEN
            quotient = number1 / number2
        ELSE
            PRINT "Division by zero is not allowed"
            quotient = "undefined" // or handle accordingly
        END IF

        // Output results
        PRINT "Iteration ", i
        PRINT "Sum: ", sum
        PRINT "Difference: ", difference
        PRINT "Product: ", product
        PRINT "Quotient: ", quotient

    END FOR

END

Explanation

1. Variable Declaration: The program starts by declaring the necessary variables for storing user inputs and results of operations.
2. For Loop: A loop runs for a fixed number of iterations (10) to allow repeated input and calculations.
3. User Input: The program prompts the user for two numbers to perform calculations.
4. Arithmetic Operations: It computes the sum, difference, and product directly. The division operation checks for division by zero.
5. Output Results: After each iteration, the results of the operations are printed along with the current iteration number.

This structure provides clear guidance for implementing the process, making it easy to convert into any programming language of choice.
