(C++) Battleship problem. Write a code by only C++ and follow the instruction clearly please.

The rules of Battleship are as follows. Each player first sets up ships on their board in secret. Each player then guesses a coordinate (letter and number combination) to bombard on the enemies board. If a ship is hit in this bombardment, the player must say Hit. If all parts of a ship are hit, then the player must say You sank my [name of ship]. If no ship was hit, the player responds miss. This process continues until one player has sunk all of the opponent's ships. Here is a website about the rules if mine are inadequate: http://boardgames.about.com/od/battleship/a/Rules-of-Battleship.htm. The pieces and lengths of pieces for Battleship are: Aircraft carrier = length 5 Battleship = length 4 Submarine = length 3 Cruiser = length 3 Destroyer = length 2 There is a lot of code here. Familiarize yourself with it some before programming (at the very least, you should look at main() and the names of all the functions in the classes). The navigator (left side of geany) can be quite useful to bounce around between methods. Your coding program can probably use Ctrl+f to search for parts of code as well. You can run the program as it is, and it should play the game Battleship for just one ship (the length 3 submarine) on a 10x10 board. For testing purposes, you could remove the randomization so you dont need to guess the whole board.

Currently, we always assume the ship is a submarine (length 3). Modify the code to make all five types of pieces possible. The possible ships are: 'D' for Destroyer 'C' for Cruiser 'S' for Submarine 'B' for Battleship 'A' for Aircraft carrier Add code so that before you start, you can select the type of ship to place. When the computer generates a random position, it should place the same type of ship as well. You must also ensure all the text is correct. For example, if you select A, your program should not say You sank the enemy submarine. The board should also use the characters above to show the type of ship on the board. In the example below an A is shown as the aircraft carrier is selected.
