Explanation:

To print all divisors of a number using a for loop, follow these steps:

Steps:

  • Take the input number (n).
  • For loop: Iterate through all numbers from 1 to n (or up to n/2, as divisors greater than n/2 can’t divide n except n itself).
  • Check divisibility: In each iteration, check if the number divides n without a remainder (n % i == 0).
  • Print the divisor: If the condition is true, print the number.

Logic:

  • Iterate from 1 to n (or n / 2).
  • If i % n == 0, then i is a divisor of n.

Explanation:

  • For input n = 12:
  • The divisors of 12 are the numbers that divide 12 evenly, which are 1, 2, 3, 4, 6, and 12.
  • The loop iterates from 1 to 12, checking each number to see if it divides 12 without a remainder.

This logic will print all divisors of any given number, including 1 and the number itself. If you want to optimize it, you can loop only up to n / 2, as no number greater than n / 2 can be a divisor of n except n itself.
