Consider the following sequence of operations:

  • Pointer p1 is set to point at a new heap-dynamic variable.
  • Pointer p2 is assigned p1’s value
  • The heap dynamic variable pointed to by p1 is explicitly de-allocated but p2 is not changed by the operation

This situation leads to which of the following:

  1. p1 becomes a dangling pointer
  2. p2 becomes a dangling pointer
  3. Both p1 and p2 are now dangling pointers
  4. Neither p1 nor p2 is now a dangling pointer
