How do I create an array in C++ which is on the heap instead of the stack?

Question

I have a very large array which must be 262144 elements in length (and potentially much larger in future). I have tried allocating the array on the stack like so:

Answer 1

I believe

#define SIZE 262144
int *myArray[SIZE] = new int[262144];

should be

#define SIZE 262144
int *myArray = new int[262144];

or better yet

#define SIZE 262144
int *myArray = new int[SIZE];
