You need to ask the user to input a number, and then input it into i.
if (i % 10 >=5; i<=14
This is definitely not right, but it's close.
1. You're missing the closing parenthesis ")"
2. you don't use semicolons inside of if statements
3. % is modulus, which is remainder of division, and you certainly don't want to sue it for this program. I don't know where you got that 10 from either.
4. Be careful, the word "between" means between and not including (at least for most tests and exams where I live).
