19.3.4 Exceptions and Constructors / Destructors

• C'tors and d'tors do not return a value
• Throwing an exception is a clean way to indicate failure
  • Caveat: Static values are initialized before main is entered. There is no try block to catch exceptions
• If a c'tor fails, the object is not created
  • The d'tor isn't called
  • Subtle source of leaks
  (See next slide)
• Two concurrent exceptions will halt the program
  • Don't throw exceptions from within a d'tor
