Question 1

Select the false statement. If an exception is thrown from a constructor:

Accepted Answer

A)  The object being constructed will not be constructed. 
B)  For an array, destructors for all array elements are called, even if those array elements have not yet been constructed. 
C)  The exception can contain the error information that the constructor would not be able to return in the normal manner. 
D)  For an object with member objects, and whose outer object has not been constructed, the destructor is called for the member objects.

C)  Return control to the function that created the exception. 
D)  Aid the terminate command in shutting down the program.

Question 3

Question 4

Which of the following is an advantage of not using exception-handling to deal with errors?

Accepted Answer

A)  Intermixing program logic with error-handling logic can make the program more difficult to read, modify, maintain and debug. 
B)  Frequent tests for infrequently occurring errors can degrade a program's performance. 
C)  Programmers may delay writing error-processing code or sometimes forget to include it. 
D)  None of the above.
