[C++] Allocating local variables

Name: Anonymous 2012-09-02 0:12

Shouldn't this be working? I'm trying to point all three pointers to this new int array, but the address isn't right.

<code>void allocate(int a[], int * &x, int ** &y, int *** &z)
{
    a = new int [ 5 ];

    x = a;
    y = new int*;
    *y = a;
    z = new int**;
    *z = new int*;
    **z = a;

    return;
}

int main()
{
    int arr[5];

    int *ptrX;
    int **ptrY;
    int ***ptrZ;

    // Allocate the dynamic memory
    allocate(arr, ptrX, ptrY, ptrZ);

    return 0;
}</code>

even then, an array isn't the same as a constant pointer. Try running this:


#include <cstdio>

int main(int argc, char** argv) {

  int arr[5];
  int* const b = new int[5];

  printf("arr = %p, &arr = %p\n", arr, &arr);
  printf("b = %p, &b = %p\n", b, &b);

  delete[] b;
  return 0;
}

no
