We have homework due tomorrow, and it's a three person group. I don't understand the slightest bit about arrays, but I've been trying - now the code just looks messy. Just with the things that say ------------------Tierra------------------, can you all help me? The book is useless and I'm just frustrated now, I don't know what to do.
