Question

I read that you can declare an aray of objects by this line

Enemy * d = new Enemy[2];

but when i tried to make a 2 dimensional array, there was an error where this cant be initialized. I also tried this

Enemy *enemies[6][2];

but i am not sure how to reference to each object in that array and and how to pass that reference to a function.

Answer 1

You need to use a pointer to a pointer in order to make a jagged array.

Enemy** d = new Enemy*[6];
for (size_t i = 0; i < 6; ++i)
    d[i] = new Enemy[2];

If you plan on making a fixed size array, you can just create it the same as you would a normal array.

Enemy enemies[6][2];

You then just reference them using two indices.

enemies[2][1].roar();

Note: You will find that multi-dimensional arrays tend to lead to more headaches than they are worth. It is much cleaner to maintain a single dimension array and simply index it based on the number of rows and columns.

Enemy* enemies = new Enemy[rows * cols];

Enemy* getEnemy(size_t row, size_t col)
{
    return enemies + (row * cols + col);
}
