Question 15

Which of the following statements is false (assume we're referring to class Time)?

Accepted Answer

A) Often a class's interface and implementation will be created and compiled by one programmer and used by a separate programmer who implements the client code that uses the class. 
B)  To hide the class's member-function implementation details, the class-implementation programmer would provide the client-code programmer with the header Time.h (which specifies the class's interface and data members) and the Time object code (i.e., the machine-code instructions that represent Time's member functions). 
C)  The client-code programmer is not given Time.cpp, so the client remains unaware of how Time's member functions are implemented. 
D)  The client-code programmer needs to know only Time's interface to use the class and must be able to link its object code.
