                                          This program will try to move a knight
                                           around a chess board to each space 
                                           exactly one time.
                                          How I will do that?
                                          I will first create the board by a determined size.
                                          I will fill the board with 0s.
                                          I will define whether a move is in bounds,
                                          and I will define whether a move is already taken
                                          I will define if there is a next move to be made 
                                            from a given space.
                          If a space is determined to be in bounds, free, and a next move
                          is possible. Then I want to write that space.

I am just getting 0s as an output. I thought this would work. Someone can tell me what Im doing wrong?
