Sinking Ships is a game in which two players place a number of ships of various length on their own board, which is hidden from the other player. Players then take turns calling out one of the tiles on their opponent’s board. Their opponent then tells them whether the shot hit or missed any of their ships. Once one player has hit every tile that contains a ship on their opponent’s board, they win the game.
Using the following UML class diagram and class descriptions to help you, create a version of Sinking Ships. The game must have one human player, and one player controlled by the computer (the computer player can be made to target random tiles). The player should be able to choose how many rows (between 10 and 26) and how many columns (between 10 and 26) the game boards should have. Players cannot shoot tiles that they have already shot, and before the human player takes their shot, they should have the option to look at their own board (showing the location of their ships and the tiles that the computer player has taken shots at and whether those shots hit or missed) or the opponent’s board (showing the tiles that the human player has taken shots at, and whether those shots hit or missed, but not showing the location of the opponent’s ships). Player input should be given as a number, to indicate the column of their chosen location, and a letter, to indicate the row (first row is A, second row is B, etc.). You may use the Sinking Ships skeleton code to help you.
