[Solved] Homework 4 Battleship

In this program you will be mimicking a game of Battleship. Your game board is a line of 10 slots. You have to implement 3 methods. The following methods must be implemented:

void setBoard(int *)

This method sets up the humans game board. The method prompts the user for 2 slots to place the ship. The program should ensure that the slots are consecutive. In other words, your ship cannot be placed at slot 2 and at slot 6. Since the board has only 10 slots, valid slots are in the range of 0 to 9.

void setComputerBoard(int *)

Exactly the same as the setBoard method except that the position of the computers ship is set randomly. The computers ship must also be in consecutive slots.

intplayGame(int *, int *)

This method should do the following steps:

1. Have the computer pick at random a slot to fire at. If the slot the computer picked on the humans board is a ship, a HIT message is displayed. If the slot on the humans board is empty, a MISS message is displayed. Print out the computers board and the humans board as described at the bottom of the page.
2. After the computer goes, have the human pick a slot to fire at. If the slot the human picked on the computers board is a ship, a HIT message is displayed. If the slot on the computers board is empty, a MISS message is displayed. Print out the computers board and the humans board as described at the bottom of the page.
3. Repeat steps 1 and 2 until there is a winner. The computer wins if both of the humans ship slots are hit. The human wins if both of the computers ship slots are hit.

The playGame method returns a 0 if the computer won. The playGame method returns a 1 if the human won.

The computer board is printed off with the following characters: (The human board is printed off similarly)

S printed off in the slots where the computers ship is located.

M printed off in the slots where the human guessed incorrectly.

H printed off in the slots where the ship is located and where the human hit.

* printed off in all other slots

You can assume the input will always be a positive integer.

Important: You should use pointer notation when referencing values inside an array as opposed to array notation. For example, use *ptrToArray instead of array[0] and *(ptrToArray+1) instead of array[1], etc. You will lose 10 points for not following this notation.

A sample run of the code is below

Enter 1st position: 4

Enter 2nd position: 5
