Write a function that accepts an 8 by 8 array of characters that represents a maze. Each position can contain either an X or a blank. Starting at position (0,1), list any path through the maze to get to location (7, 7). Only horizontal and vertical moves are allowed. If no path exists, write a message indicating there is no path.

Moves can be made only to locations that contain a blank. If an X is encountered, that path is blocked and another must be chosen. Use recursion.

Addition specifications: The two dimensional array will be stored in a file. The filename will be passed as a command line parameter to main(). Instead of spaces, the letter O will indicate an open position. The only loop allowed in the program is the one to read in the maze from the file. The recursive function, find_path(), may only call itself and printf(). Hints: To avoid an infinite recursion, when you first come to a location in the maze, you should mark it with an 'X'. Just because you must print them out starting at (0,1), does not mean that your recursion must start there.
