Deck 1: Software Engineering Principles and C++ Classes

Question 1

A program goes through many phases from the time it is first conceived until the time it is retired, called the life cycle of the program.

Answer 1

True

Question 2

The three fundamental stages through which a program goes are implementation, use, and maintenance.

Answer 2

False

Question 3

In the software maintenance process, the program is modified to fix the (identified) problems and/or to enhance it.

Answer 3

True

Question 4

A program that is well developed is more expensive to maintain.

Question 5

Software engineers typically break the software development process into the following four phases: analysis, design, implementation, and testing and debugging.

Question 6

Dividing a problem into smaller subproblems is called structured design.

Question 7

The structured design approach is also known as modular programming.

Question 8

Encapsulation is the ability to handle data and operations as separate units.

Question 9

In OOP, each object consists of data and operations on that data.

Question 10

OOD has three basic principles: encapsulation, inheritance and polymorphism.

Question 11

Encapsulation is the ability to create new data types from existing data types.

Question 12

Polymorphism is the ability to use the same expression to denote different operations.

Question 13

A postcondition is a statement specifying what is true before the function call is completed.

Question 14

In black-box testing, you do not know the internal working of the algorithm or function.

Question 15

White-box testing relies on the internal structure and implementation of a function or algorithm.

Question 16

The term asymptotic means the study of the function f as n becomes larger and larger without bound.

Question 17

The components of a class are called objects.

Question 18

If g(n) = 1, the growth rate is constant and does not depend on the size of the problem.

Question 19

In C++, the mechanism that allows you to combine data and the operations on that data in a single unit is called a class.

Question 20

The members of a class are classified into three categories: private, public, and main.

Question 21

Private, public, and protected are member access specifiers.

Question 22

Class objects cannot be passed as parameters to functions or returned as function values.

Question 26

The structured design approach is also known as ____.

D) stepwise updating

Question 27

____ is the ability to create new data types from existing data types.

A) white-box and blue-box
B) black-box and blue-box
C) white-box and green-box

B) g(n)=log₂n
C) g(n)=nlog₂n

Question 31

In the function ____, the growth rate is quadrupled when the problem size is doubled.

A) g(n)=1
B) g(n)=nlog₂n
C) g(n)=n²
D) g(n)=2ⁿ

Question 32

In the function ____, the growth rate is exponential.

A) g(n)=1
B) g(n)=n²
C) g(n)=nlog₂n
D) g(n)=2ⁿ

Question 33

A(n) ____ is a collection of a fixed number of components.

A) object
B) member
C) class
D) friend

Question 34

The members of a class are classified into three categories called ____ access specifiers.

A) member
B) object
C) function
D) object.

Question 35

Deciding which member to make private and which to make public depends on the ____ of the member.
