Question

Write a program to input any number and display its prime factors using a function with an argument but not return value

Answer 1

The student asked for a program to display the prime factors of a number using a function with an argument and no return value. The solution provided is a Python program that defines a function to print the prime factors of the given number.

Step-by-step explanation:

The question asks for a program that inputs any number and displays its prime factors using a function. The function should take an argument, the number to factorize, and it should not return any value but print the prime factors directly.

Here's an example of how one might write such a program in Python:

def print_prime_factors(number):

# Starting with the smallest prime factor

divisor = 2

while number >= divisor:

if number % divisor == 0:

print(divisor)

number = number / divisor

else:

divisor += 1

# Input from user

num = int(input("Enter any number:"))

print("The prime factors are:")

print_prime_factors(num)

This program defines a function print_prime_factors that takes an integer and prints its prime factors. It starts with the smallest prime, 2, and divides the number by it (if possible) until it can't be divided by 2 anymore, then it increments the divisor and continues the process until the number is reduced to 1. The main part of the program takes an input from the user and then calls the function to print the factors.
