So here goes the first challenge:
Write a winform ASCII lawn mowing application with these properties:
- It should start with a 10x10 grid of capital "X"'s.
- The lawn mower should be represented by an "@" symbol, and start in the upper left hand corner.
- The user should be able to use the arrow keys to move the lawnmower around the lawn.
- The first time the lawn mower passes over an X, it gets converted to a lower case "v".
- When the lawn mower passes over a "v", it gets converted to a ".".
- When the entire lawn has been reduced to "."'s a message should be displayed to the user.
Good luck and happy mowing!
