It's basically asking you to create a function called 'even' that returns a 0 if odd and 1 if even. So I would start by creating a function, I'm pretty sure there are enough hints in the thread to go about creating it, but since you still seem pretty confused:

Code:
int even(int input)
{
   return (input % 2 == 0);
}
Now you should be worrying about how to get the actual series of integers, theres a number of ways of going about doing this - one of the simpler options is to ask the user how many integers that are expecting and then keep reading in integers and storing it in an array or something. Once you read in all the integers (and processed them using even()) simply just print the array out. I'm pretty sure there are more efficient ways though
