The throw keyword is used to perform which two actions? (Choose two.)

  1. stop processing of the code

Answer: C,D

Explanation: * The Throw statement throws an exception that you can handle with structured exception-handling code (Try…Catch…Finally) or unstructured exception- handling code (On Error GoTo).
