Question 1

A software product is developed in a sequence of stages known as a life __________.

Accepted Answer

cycle

Question 2

A(n) __________ specification for a new software product should be generated at the beginning of a project.

Accepted Answer

requirements

Question 3

When designing software using __________ refinement, you start at the top level (the original problem) and divide it into subproblems.
A) piecemeal
B) iterative
C) stepwise
D) incremental

Accepted Answer

Stepwise refinement is a methodology where you start with a high-level overview of a problem and then break it down into more manageable subproblems. This approach allows for a more structured and systematic development process.

Question 4

Looking at the nouns in the problem statement can help you identify objects, and looking at the verbs can point to the __________.

Accepted Answer

The answer of Looking at the nouns in the problem...

Question 5

The common characteristics of a collection of similar objects define a class, and the interactions are identified as __________ that one object sends to another.

Accepted Answer

The answer of The common characteristics of a collection of...

Question 6

An abstraction is a model of a physical entity or activity.

Accepted Answer

An abstraction is a simplified model of something complex, used for understanding or representing its essential aspects while omitting irrelevant details. This applies to both physical entities and activities.

Question 7

In the __________ view of a data object, you can describe what information is stored in the data object without being specific as to how the information is organized and represented.

Accepted Answer

The answer of In the __________ view of a data...

Question 8

In C++, the operators are called member __________.
A) functions
B) procedures
C) routines
D) methods

Accepted Answer

In C++, the operators when defined inside a class are called member functions. These functions operate on the objects of the class, allowing for operator overloading and other object-oriented programming features.

Question 9

In C++ there are two kinds of types: the __________ and the class types.
A) basic
B) programmer-defined
C) user-defined
D) primitive

Accepted Answer

The answer of In C++ there are two kinds of...

Question 10

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

Accepted Answer

Members declared in the private part of a class definition are accessible only within the class itself or by friends of the class, not by any other classes.

Question 11

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

Accepted Answer

The answer of The preprocessor directives ifndef, define, and __________...

Question 12

Which keyword should you insert in the member function defined below to protect "hours" from modification?
Int Clock::get_hours() __________ {
Return hours;
}
A) private
B) public
C) const
D) protected

Accepted Answer

The keyword "const" should be inserted at the end of the member function declaration to indicate that the function does not modify any member variables of the class. This ensures that "hours" is protected from modification when the function is called.

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;

Accepted Answer

The "static" modifier means that VOTE_AGE is a class-level variable, shared among all instances of the class, rather than being duplicated in each instance.

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

Accepted Answer

A constructor is a special type of member function in a class that is automatically called when an object of that class is created. Unlike regular member functions, constructors do not have a return type, not even void.

Question 15

If we want to allow a class user to update or modify the value of a data field, we provide a __________ function beginning with the word set and ending with the name of the data field (for example, set_given_name).
A) modifier
B) constant
C) change
D) static

Accepted Answer

Modifier functions, often called setters, are used to update or modify the value of a class's data field. They typically start with "set" followed by the name of the data field they are designed to modify.

Question 16

In the context of the function header below, the operator "!=" is __________.
Bool operator!=(const Person& per) const;
A) overridden
B) overloaded
C) promoted
D) undefined

Accepted Answer

The operator "!=" is overloaded in this context, allowing for custom comparison between instances of the Person class or between a Person instance and other data types, depending on the implementation.

Question 17

Which of the following functions correctly condenses the body of can_vote () appearing directly below.
Bool Person::can_vote(int year) const {
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;
 }
B) bool Person::can_vote(int year) const {
 return age(year) >= VOTE_AGE;
 }
C) bool Person::can_vote(int year) const {
 return the_age >= age(year);
 }
D) bool Person::can_vote(int year) const {
 return the_age >= VOTE_AGE;
 }

Accepted Answer

Option B is correct because it directly returns the result of comparing the age of the person in the given year with the constant VOTE_AGE, which matches the logic of the original function.

Question 18

The expression __________ is a reference to the object pointed to by "this".

Accepted Answer

The answer of The expression __________ is a reference to...

Question 19

A test that demonstrates that certain requirements of a particular class are met is called a __________ test.
A) specification
B) use
C) driver
D) unit

Accepted Answer

A unit test is a test that demonstrates that certain requirements of a particular class are met.

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).

Accepted Answer

The answer of One way to make code reusable is...
