D) primitive

Question 10

Members declared in the private part of a class definition can be accessed by any other class.

Question 11

The preprocessor directives ifndef, define, and __________ are used to prevent multiple definitions of the identifiers in header files.

Question 12

Int Clock::get_hours() __________ {
Return hours;
}

A) private
B) public
C) const
D) protected

Question 13

In the code segment below, the modifier "static" indicates that the constant VOTE_AGE is being defined for the class and does not have to be replicated in each instance.
static const int VOTE_AGE = 18;

Question 14

A constructor differs from a member function in that it has no __________.

A) local variables
B) name
C) parameter list
D) return type

Question 15

B) constant
C) change
D) static

Question 16

Question 17

Which of the following functions correctly condenses the body of can_vote () appearing directly below.

Int the_age = age(year);
/* VOTE_AGE is a private data member of Person class*/
Return the_age >= VOTE_AGE;
}

A) bool Person::can_vote(int year) const {
return age(year) >= the_age;
}

A) specification
B) use
C) driver
D) unit

Question 20

One way to make code reusable is to __________ or combine a group of data elements representing an object together with its operations (functions and operators) in a separate program module (a class).

Question 21

Question 22

The classes that declare the data fields and code member functions that perform the operations are said to __________ the ADT.

A) define
B) construct
C) implement
D) specify

Question 23

An ADT is a(n) __________ between the ADT designer and the programmer who codes a class that implements the ADT.

Question 24
