Question 1

Select the false statement.

Accepted Answer

A)  C++ includes object serialization by default. 
B)  After a serialized object has been written to a file, it can be read from the file and deserialized-that is, the type information and bytes that represent the object and its data can be used to recreate the object in memory. 
C)  When an object is output to disk, only the values of its attributes are output. 
D)  None of the above.
