Line maze solver/w shortest path algorithm

[AwesomeDeepesh]

hello every one....
I am trying to make a line maze solver with the shortest path algorithm
and I need a little help I have attached the code please have a look at it and help me out
and please tell me if I can do anything to replace the 999999999999999999999999999999
in my code




Thanks in advance to anyone who tries to help me out

You are going to need some datastructures to represent the maze.  Is that what the path thing is for?

Code: [Select]

char path[999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999]

I don't think my PC even has enough memory to hold that array, and it has 8,000,000 times as much memory as a Uno.

i have changed the 99999999999999999999999999999999999999999999999999999999999 to 500

i have hanged the 99999999999999999999999999999999999999999999999999999999999 to 999

And? What happened?

I got the algorithm from here and I am not able to complete it...
I have fixed some parts of the code please review it
I am having trouble with the cancellation part

[AwesomeDeepesh]

please review my updated code

The code you posted does what? How does that differ from what you want?
