Module 9: Odds and Ends Questions Question 1 How is the static_cast operator different from the dynamic_cast operator? Question 2 Which of the following are not examples of correct usage (conceptually or syntactically) of auto ptr? (Assume the needed header files have beenincluded.) auto ptr int> pia(new int[20]) auto ptr str> (new string); int ngue = 7; auto_ptr int pr(&rigue): auto ptr dbl (new double) Question 3 Give at least three examples of convenience advantages that a vector object has over an ordinay array.
