int *array[10] to dynamic array equivalent?

[vvtc]

Hi,

What is the dynamic array equivalent to this?

int *array[10]

---

int *array
array = new int[10]

I want something like the above, but I can't seem to figure out the correct way to do it

Any help would be appreciated!

Thanks!

int** array = 0;
// allocate first dimension
array = new int*[10]; // array of 10 pointers

Thank you very much!

Ok, I'm stuck again. So if I have

int** array = 0;
// allocate first dimension
array = new int*[10]; // array of 10 pointers

How do I pass the array into function calls?
I have it as:

function( array[some_index] );

function(int *&head)
{
   array = new int; 
}

and it seems to work without and compilation errors, but it seems to me that whatever I do in the function to the array has no effect ( I passed it in by reference in the function call )

>>function(int *&head)
That is not a function that takes a 2d array. What you have there is a reference to a 1d array. They are not the same thing.

void functijon(int **array)
{
  array[0][1] = 123;
}

The above is a 2 dimensional array of integers. The first dimension is an array of pointers. You still have to allocate the second dimension before the above will work

int main()
{
    int **array;
   array = new int*[10];
   for(int i = 0; i < 10; i++)
  {
      array[i] = new int[20];
      for(int j = 0; j < 20; j++)
          array[i][j] = 0;
  }
}

void functijon(int **array)
{
  array[0][1] = 123;
}

The above is a 2 dimensional array of integers.

Not really. array is a (misnamed) pointer to a pointer. It is not a 2D array. However, in some circumstances (eg the code example you gave, although I won't quote that again) a pointer to pointer can be treated as if it is a 2D array.
