Exception Handling

• This automatic invocation of destructors only applies to objects.
• Consider the following code.

  Product* p = new Product();
  if (p->read())
  {
     ...
  }
  delete p; // never executes if read throws an exception
  

• If an exception occurs in the read function, p receives no special attention because it is not an object.
• A memory leak occurs.
