Answer 4

You could look at the numbers binary form using the & operator instead of performing a modulus operation (which takes more time)

//below looks at the least significant bit or the bit on the far right if it is a 1 then it is always odd, if 0 then it is even.

if(num->n & 1)
{
printf("odd");
}
else
printf("even");

return 0;
