Answer 1

1. You are trying to delete a variable allocated on the stack. You can not do this
2. Deleting a pointer does not destruct a pointer actually, just the memory occupied is given back to the OS. You can access it untill the memory is used for another variable, or otherwise manipulated. So it is good practice to set a pointer to NULL (0) after deleting.
3. Deleting a NULL pointer does not delete anything.
