Ok, first thing you need it that exercise is to create an array and fill it with values: var a: array[10, int] for i in 1 .. 10: a[i-1] = 10*i Run Now comes the part you're struggling with: for i in 0 .. 9: if i mod 2 != 0: echo a[i] Run There are of course (as shown above) other ways to do it, but this is how I (if I were a beginner :)) would do it.
