Question
Write a c++ program with the following specifications:
The program should simulate a one-player game of battleship. The user should be able to specify the board size and the number of ships that will be placed on the board. (Ships should be of varied sizes.) Once the program generates the board with random ship placement, the user should be able to specify coordinates and have the game show them whether a "hit" or "miss" has occurred and display the resulting screen. Additional rules may be specified as needed.
Program structural requirements:
The board will be constructed with a dynamic array
The collection of ships will be stored with a linked list
