Apus

Console game which follows the rules of “minesweeper”.

Introduction

In minesweeper the objective is to find mines hidden on a board. The computer game will generate a board (in our case 8x8) and randomly place 8 mines somewhere on the board. The player progressively reveals the board by “sweeping” a location. When the player does this they are informed of the number of mines surrounding the selected location.

For our game we will use the following key:

• for a location which has yet to be revealed A number (0-8) which will identify the number of mines surrounding a location Note: A 0 would indicate all the surrounding locations are mine free. A letter (m) to indicate a mine

Below is an example of a fully explored board: (for clarity this example contains only 3 mines, rather than 8)

m 1 0 0 0 0 0 0
1 1 0 1 1 1 0 0
0 0 0 1 m 1 0 0
0 1 1 2 1 1 0 0
0 1 m 1 0 0 0 0
0 1 1 1 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0

Rules

• Where we see “2” this indicates that on the eight squares surrounding that location, there are 2 mines.
• Where we see “1” this indicates that on the eight squares surrounding that location, there is 1 mine.
• Where we see “0” this indicates that all eight surrounding locations are safe.
• Although this example only shows digits 0, 1 and 2 it is possible that any number between 0 and 8 could be shown.

Objective

Write a console app which will:

• Construct an 8 x 8 board with 8 randomly distributed mines. Keep this hidden from the player.
• Via the console print out the 8 x 8 board to the player using an asterisk (*) to indicate a hidden location. At the start all locations are hidden. Make sure to show the player the number of adjacent mines for the squares they have already revealed. The grid should have row and column identifiers. (see example sequence below.)
• Ask the player for the location they wish to reveal.
• If the selected location is empty:
  • Print the entire board to the console again and reveal the number of adjacent mines to the player.
  • If all the unrevealed locations contain mines: Tell the player they won and end the program.
  • If there are still hidden mines: go back to the beginning and ask the player for the coordinates of another location to reveal.
• If the selected location contains a mine:
  • Reveal the entire board with all mines and numbers shown. Then end the program. (note: if the player is unlucky, this could be their first turn!)

Example

For the following example assume the board hidden from the player is:

m 1 0 0 0 0 0 0
1 1 0 1 1 1 0 0
0 0 0 1 m 1 0 0
0 1 1 2 1 1 0 0
0 1 m 1 0 0 0 0
0 1 1 1 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0

The first board shown to the player is:

   A B C D E F G H
1  * * * * * * * *
2  * * * * * * * *
3  * * * * * * * *
4  * * * * * * * *
5  * * * * * * * *
6  * * * * * * * *
7  * * * * * * * *
8  * * * * * * * *

Please enter a column and row (e.g. A8):

If the player types H8 the board is revealed as:

   A B C D E F G H
1  * * * * * * * *
2  * * * * * * * *
3  * * * * * * * *
4  * * * * * * * *
5  * * * * * * * *
6  * * * * * * * *
7  * * * * * * * *
8  * * * * * * * 0

Please enter a column and row (e.g. A8):

If the player types D4 the board is revealed as:

   A B C D E F G H
1  * * * * * * * *
2  * * * * * * * *
3  * * * * * * * *
4  * * * 2 * * * *
5  * * * * * * * *
6  * * * * * * * *
7  * * * * * * * *
8  * * * * * * * 0

Please enter a column and row (e.g. A8):

If the player types A1 (and a mine is hit) the complete board is revealed:

   A B C D E F G H
1  m 1 0 0 0 0 0 0
2  1 1 0 1 1 1 0 0
3  0 0 0 1 m 1 0 0
4  0 1 1 2 1 1 0 0
5  0 1 m 1 0 0 0 0
6  0 1 1 1 0 0 0 0
7  0 0 0 0 0 0 0 0
8  0 0 0 0 0 0 0 0
