Answer:
1)  its because we managed to divide the answer so it is not a prime number.
2)
Code:
#include <stdio.h>
int main()
{
    int i, j, n, isPrime; // isPrime is used as flag variable
    /* Input upper limit to print prime */
    printf("Enter your n : ");
    scanf("%d", &n);
    printf("Prime numbers from 1 to %d:\n", n);
    /* Find all Prime numbers between 1 to n */
    for(i=2; i<=n; i++)
    {
        /* Assume that the current number is Prime */
        isPrime = 1;  
        /* Check if the current number i is prime or not */
        for(j=2; j<=i/2; j++)
        {
            /*
             * If i is divisible by any number other than 1 and self
             * then it is not prime number
             */
            if(i%j==0)
            {
                isPrime = 0;
                break;
            }
        }
        /* If the number is prime then print */
        if(isPrime==1)
        {
            printf("%d,\n ", i);
        }
    }
    return 0;
}
