memory leak

To C++ experts,

 suppose I have this code :
--------------------------------
  int **p = new int*[dim1] ;
  for(int i=0; i<dim1; i++)  p[i] = new int[dim2] ;

  for(int i=0; i<dim1; i++)
    for(int j =0; j< dim2; j++) p[i][j] = i*j ;
--------------------------------
    Then how do I  free the memory ?
    Also, in general, is there a way to check the memory leak or keep  
    track of the memory usage ?

    Thanks.

// Delete the memory allocated to each of the sub-arrays
for (i = 0; i < dim2; i++) {
     delete[] p[i];
}

// Then delete the memory for the main array p
delete[] p;

If you are using VC++ then there are some tools out there that claim to be able to do just this, but whether they work or not is a different matter.  I have never used any.

BTW, linking in with your next question, it should be clear now that this memory is allocated on the HEAP.

PS it is not advisable to post the same question in a separate topic, you should post a 20 point Q with a link to this one, or request a zero point pointer question from community support.  That way you can delete it yourself.
