Note this is in the C++ forum, Arizona Web ;) However, we do need more information. How do you want to write these numbers? Do you want to write them to the screen? To an array? Remember, we can use modular division (%) to pick out even numbers. Mod division is like remainder division. So if we said, check to see if number (n % 2) == 0 it would divide n by 2, and if the remainder was equal to zero, we would know the number was even.
