TRUE/FALSE

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.

ANS:T PTS:1 REF:2

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

ANS:F PTS:1 REF:2

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

ANS:T PTS:1 REF:2

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

ANS:F PTS:1 REF:3

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

ANS:T PTS:1 REF:3

6.Dividing a problem into smaller subproblems is called structured design.

ANS:T PTS:1 REF:4

7.The structured design approach is also known as modular programming.

ANS:T PTS:1 REF:4

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

ANS:F PTS:1 REF:4

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

ANS:T PTS:1 REF:4

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

ANS:T PTS:1 REF:4

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

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

ANS:T PTS:1 REF:4

13.A precondition is a statement specifying the condition(s) that must be true before the function is called.

ANS:T PTS:1 REF:5

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

ANS:F PTS:1 REF:6

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

ANS:T PTS:1 REF:7

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

ANS:T PTS:1 REF:8

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

ANS:T PTS:1 REF:14

18.The components of a class are called objects.

ANS:F PTS:1 REF:17

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

ANS:T PTS:1 REF:17

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

ANS:T PTS:1 REF:17

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

ANS:F PTS:1 REF:18

22.Private, public, and protected are member access specifiers.

ANS:T PTS:1 REF:18

23.A class and its members can be described graphically using a notation known as Unified Modeling Language (UML) notation.

ANS:T PTS:1 REF:22

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

ANS:F PTS:1 REF:32 2 / 4

25.As parameters to functions, class objects can be passed only by reference.

ANS:F PTS:1 REF:32
