C Programming: Read an integer and find all its divisor

Sample Solution:

C Code:

#include <stdio.h>
int main() {
    int x, i;

    // Get an integer input from the user
    printf("\nInput an integer: ");
    scanf("%d", &x);

    // Print all the divisors of x
    printf("All the divisors of %d are: ", x);
    for(i = 1; i <= x; i++) {
        if((x%i) == 0){
            printf("\n%d", i);
            printf("\n");
        }
    }

    return 0;
}

Sample Output:

Input an integer: 45                                                   
All the divisor of 45 are:                                             
1                                                                      
                                                                       
3                                                                      
                                                                       
5                                                                      
                                                                       
9                                                                      
                                                                       
15                                                                     
                                                                       
45
