Print All Factors of a Number.

#include <stdio.h>

int main() {
    int num, i;

    // Asking the user for input
    printf("Enter a positive integer: ");
    scanf("%d", &num);

    // Check all numbers from 1 to num to find factors
    printf("Factors of %d are: ", num);
    for (i = 1; i <= num; i++) {
        // If num is divisible by i, then i is a factor
        if (num % i == 0) {
            printf("%d ", i);
        }
    }

    return 0;
}

Explanation:

The program prints all numbers that divide num evenly, which are its factors.

Variables:

num: Stores the number entered by the user.

i: Loop variable used to check divisibility.

User Input:

The user is prompted to enter a number, which is stored in num.

Loop to Find Factors:

A for loop runs from 1 to num.

For each i, the program checks if num % i == 0.

If true, i is a factor and is printed.

Output:

Enter a positive integer: 28
Factors of 28 are: 1 2 4 7 14 28
