## IV favorites ] smart ptr

  1. shared ptr in container
  2. deleter
  3. unique ptr
  4. how is ref count maintained
  5. thread safety
  6. skeleton of a smart ptr

Other things they may not ask but I could demonstrate:

  1. weak ptr
  2. pitfalls like “starting a new club”
  3. use as field, esp in a RAII host class
  4. const ptr to const object?
  5. pbref^pbclone
  6. factory always returns (smart?) pointers
