C 함수에서 2D 배열을 안전하게 반환하고 관리하는 방법은 무엇입니까?

int** create2DArray(unsigned height, unsigned width)
{
    int** array2D = 0;
    array2D = new int*[height];

    for (int h = 0; h < height; h++)
    {
        array2D[h] = new int[width];

        for (int w = 0; w < width; w++)
        {
            // Initialize array elements as needed
        }
    }

    return array2D;
}

int height = 15;
int width = 10;
int** my2DArray = create2DArray(height, width);
// Use the array as needed
// ...
for (int h = 0; h < height; h++)
{
    delete [] my2DArray[h];
}
delete [] my2DArray;
my2DArray = 0; // Set pointer to null to prevent dangling pointer
