else
// here the number is more tham 1. so, stop repeating. break
break;
}
// check if num is even or odd
// if the number is odd, we will have remainder when divided by 2 is ZERO
// ie., num%2==0==> EVEN else, num is ODD
if(num%2==0)
printf("%d is Even Number.",num);
else
printf("%d is Odd Number.",num);
printf("\nPlease press any key to continue..");
