While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.
So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.
And the code you show doesn't appear to be even slightly related to the assignment. Where is the fixed size maze you are instructed to create in the first part? Without that, you can't even begin to start the second part. and this doesn't do that:
Go back to the assignment and read it again: then throw that code away and start by doing exactly what it tells you to.
And do yourself two favours:
1) Indent your code properly and consistently. It makes it a lot easier to read and that means more reliable and maintainable.
2) Stop using single character names for all variables: use names that are descriptive of their purpose.
