#include <stdio.h>


int main (void)
{
int i, nb, count, test;
test = count = 0;
printf ("enter integer: ");
if (scanf ("%d", &nb) != 1)
return -1;

for (i = 2; i < nb; i++, count++)
if (nb % i == 0)
test = 1;
if (!test)
printf ("%d prime number, number of iterations = %dn",
nb, count);
else
printf ("%d is not a prime number, number of iterations
= %dn", nb,count);
return 0;
}
