Pointer and memory allocation problem

**Dual-Catfish** · 02-16-2002

Alright, I'm making an object oriented Battleship game, there are 2 classes, 'Ship' and 'Board'

The board is the ocean that the ships are placed in, and there are 2 objects of this class for every game that is played.

The class contains a member variable m_oceanArray of type short int.

Code:

short int *m_oceanArray;

The classes constructor then trys to initalize this pointer to a size of [x] and [y]. X and Y are two values passed to the constructor, based on the users input.

Code:

m_oceanArray = new short int[x][y];

I'm probably doing something horribly wrong, but I don't know what! Logic suggests I have to use something like realloc() to do this, but I'm unsure..

Thanks in advance.

Theres some code here that will show you what you need to do.

Code:

bool **m_shipsDamage;
short int **m_shipsLength;

Code:

Ship::Ship(short int length)
{

	m_shipsDamage = new bool * [2];
	m_shipsLength = new short int * [2];

	for (short int i = 0; i < 2; i++)
	{
		m_shipsDamage[i] = new bool[length];
> 		m_shipsLength[i] = new short int * [2];
	}
};

> BattleshipV2.cpp(182) : error C2440: '=' : cannot convert from 'short ** ' to 'short *' Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast.

I have no idea what this is.. nor how to fix it.. I got a few other errors when making a refrence to the matrix, but I fixed it by sticking a * infront.
