You're right I don't get your point. These ARE simple coding tasks; there's nothing complicated about making squares, triangles etc of characters on a text mode screen. If the OP can't do these tasks then they won't be able to do more complicated ones, and the teacher won't be able to see why because they handed in a perfectly good basic task (that you wrote for him - you don't think the OP will credit you on that homework assignment do you?).
