Due Date: November 23

NO LATE SUBMISSIONS.

Windows 95 comes with a game called Minesweeper.
The game is played on a grid; some squares on the grid contain mines.

Write a program that reads a file that contains the number
of rows and columns in the grid, and then the grid.
The grid will have squares marked o; those are mines.
Other squares do not have mines and will have ?.

Your output will output the grid. Mines will still have o's.
Squares that do not have mines will be replaced by a number
that indicates the number of adjacent mines (the maximum will be 8).

Here is a sample input file
5 5
?o???
o??o?
??o?o
oo?o?
?o???

The output file is
2o211
o33o2
34o4o
oo4o2
3o311

Use an apmatrix of appropriate type to represent the input grid.
You must verify that the input file is respectable (i.e. the
rows and columns make sense, and you really read the correct number
of rows and columns).

HAND IN: Your source code and program output.
  Use the file data8.txt, which is on the Web page.

The due date is Wednesday, November 18 at CLASS TIME
and there will be a quiz at the start of class
concerning matrices.
