Output - Python Programming Exercise

This Python program prompts the user for two integer numbers and calculates their product without using the "*" operator. Instead, it uses consecutive additions to simulate multiplication. For instance, multiplying 3 by 5 is achieved by adding 3 five times: 3 + 3 + 3 + 3 + 3 = 15. This approach helps reinforce the concept of repetitive operations and is an excellent exercise for understanding the fundamental mechanics behind multiplication. It also showcases how to implement loops and user inputs in a Python program. This exercise is valuable for beginners looking to enhance their problem-solving skills and grasp the inner workings of mathematical operations in programming. By avoiding the use of the direct multiplication operator, it encourages the use of iteration and conditional logic to achieve a desired result.

 Objective

Develop a Python program that prompts the user for two integer numbers and displays their product without using the "*" operator. It should use consecutive additions. (Hint: remember that 3 * 5 = 3 + 3 + 3 + 3 + 3 = 15)

 Example Python Exercise

 Copy Python Code 
# Prompt the user to enter the first number
num1 = int(input("Enter the first number: "))

# Prompt the user to enter the second number
num2 = int(input("Enter the second number: "))

# Initialize the product variable
product = 0

# Use a while loop to calculate the product using consecutive additions
i = 0
while i < num2:
    product += num1
    i += 1

# Display the product
print(f"The product of {num1} and {num2} is {product}")

 Output

Enter the first number: 3
Enter the second number: 5
The product of 3 and 5 is 15
