Question

Imagine we are using a two-dimensional array as the basis for creating the game battleship. In the game of battleship a '~'character entry in the array represents ocean (i.e., not a ship), a '#' character represents a place in the ocean where part of a ship is present, and an 'H'character represents a place in the ocean where part of a ship is present and has been hit by a torpedo. Thus, a ship with all 'H' characters means the ship has been sunk. Declare a two-dimensional array that is 25 times 25 that represents the entire ocean and an If statement that prints "HIT" if a torpedo hits a ship given the coordinates X and Y. Write a C++ program that will read in a file representing a game board with 25 lines where each line has 25 characters corresponding to the description above. An example file might look like: You should write a function called Fire that will take an X and Y coordinate and print "HIT" if a ship is hit and "MISS" if a ship is missed. If a ship is HIT you should update the array with an 'H' character to indicate the ship was hit. If a ship is hit that has already been hit at that location you should print "HIT AGAIN". You should write a second function called FleetSunk that will determine if all the ships have been sunk. Your C++ program must then call these functions until all the ships have been sunk, at which point the program should display "The fleet was destroyed!".
