    When use a delegate?

    When would you choose to use a delegate rather than calling a function
    directly? What's the advantages? Thanks...

      One prime example is events.

      Another is when you have to run more than one "function" when a specific
      action happens.

      Another is when you have a library that has to make a callback to the
      calling application, but you do not know what the event name is at the time
      you create the library.

          Sometimes you don't know what function you're going to want to call, only
          its signature. Delegates allow you that flexibility.
