Error using cout with pointer value

I have problem in the following code:

int *ary = new int[2];
ary[0] = 1;
ary[1] = 2;

cout << &ary[0];   //no error
cout << &ary[0] + " " + &ary[1];  //error (expression must have integral or unscoped enum type  )

I cant understand why arise error using pointer value with string(integral)

cout "streams" data into the standard output using the << operator. Not the + operator.

cout << &ary[0] << " " << &ary[1];

The way you wrote it before attempted to add 2 int* with a char[2], which aren't valid types to add with each other.
