+
+> What is the type of the exception object in the following throws?
+> 
+> **(a)**`range_error r("error");`
+> `throw r`;
+> **(b)**`exception *p = &r;`
+> `throw *P;`
+
+>What would happen if the `throw` in **(b)** were written as `throw p`?
+
+	The type of the exception object in (a) is range_error which is used to report range errors in internal computations.
+	The type of the exception object in (b) is exception.
+	If the "throw" in (b) were written as "throw p", there will be a runtime error.
