Need help with Get and Set class functions and class constructor

[wte0001]

Hey there,

I have an assignment that I'm working on that I feel I am very close to finishing. Basically the idea is that I need to read in a "maze" from a text file that looks something like this:

A E B * *

B * * * A

C G * * *

D H * * *

E * F A *

F J G * E

G K H C F

H * * D G

I * J * *

J * * F I

K * L G *

L * * * K

Then,using classes and pointers, I need to construct the maze, where each line above is a "Node".
The first character in the line is the name of the "Node". The next character to the right is the Node located directly North, then next character is the node that is located east of the node, then next is south, then next is west. If there is a "*". That means there is no node in that direction. The maze is done when I navigate correctly from Node A to Node L.

If done correctly, it will look something like this:

===========================================================
| Welcome to Tiger Maze! |
===========================================================
Enter the graph configuration file name: graphConfig1.txt
Maze graph construction completed.
You are currently in Room A of the Amazing Maze, you can go North or East. What is your choice? N
You are currently in Room E of the Amazing Maze, you can go East or South. What is your choice? E
You are currently in Room F of the Amazing Maze, you can go North, East or West. What is your choice? E
You are currently in Room G of the Amazing Maze, you can go North, East, South or West. What is your choice? N
You are currently in Room K of the Amazing Maze, you can go East or South. What is your choice? E
Congratulations! You have reached the finish point.
You took 5 steps.

I believe I almost have it complete, but I am having difficulties constructing the get and set statements, as well as the class constructor. Any help on this matter would be much appreciated. Thank you!

Code thus far:

Is that better? :)
