Q501.
What is the main drawback of using the number of lines of code as a complexity metric?

a.

It's difficult to compare programs written in different languages

b.

It's hard to compare different pieces of software

c.

It's subjective

d.

Both a and b

Discuss
Answer: (d).Both a and b Explanation:There are two main objections to the direct use of the number of lines of code as a complexity metric. One is that it makes it hard to compare different pieces of software due to differences in verbosity of different programmers. The other is that it makes it hard to compare programs written in different languages.
Q502.
What is Halstead's work known for?

a.

Defining the notion of operator and operand

b.

Being the first major work to point out the potential of software metrics for software development

c.

Deriving complexity metrics based on the structure of software

d.

Relating complexity to the average number of variables for which information must be kept by the reader

Discuss
Answer: (b).Being the first major work to point out the potential of software metrics for software development Explanation:Halstead's work has been very influential and it was the first major body of work to point out the potential of software metrics for software development.
Q503.
What is the second class of intra-modular complexity metrics based on?

a.

Operator and operand definitions

b.

The structure of the software

c.

The use of data structures

d.

The reader's comprehension of the program text

Discuss
Answer: (b).The structure of the software Explanation:The second class of intra-modular complexity metrics concerns metrics based on the structure of the software.
Q504.
What is the complexity metric based on the use of data structures concerned with?

a.

The structure of the software

b.

The control flow of the program

c.

The number of instructions between successive references to one and the same object

d.

The average number of variables for which information must be kept by the reader

Discuss
Answer: (c).The number of instructions between successive references to one and the same object Explanation:If the complexity metric is based on the use of data structures, it may be done so by considering the number of instructions between successive references to one and the same object.
Q505.
What is the best-known complexity metric from the class of structure-based complexity metrics?

a.

The use of data structures

b.

McCabe's cyclomatic complexity

c.

The average number of variables for which information must be kept by the reader

d.

The structure of the software

Discuss
Answer: (b).McCabe's cyclomatic complexity Explanation:The best-known complexity metric from the class of structure-based complexity metrics is McCabe's cyclomatic complexity.
Q506.
What does McCabe base his complexity metric on?

a.

The use of data structures

b.

A (directed) graph depicting the control flow of the program

c.

The structure of the software

d.

The reader's comprehension of the program text

Discuss
Answer: (b).A (directed) graph depicting the control flow of the program Explanation:McCabe bases his complexity metric on a (directed) graph depicting the control flow of the program.
Q507.
What is the formula for McCabe's cyclomatic complexity?

a.

CV=e-n+p+1

b.

CV=n-e+p+1

c.

CV=e+n-p+1

d.

CV=n+e-p-1

Discuss
Answer: (a).CV=e-n+p+1 Explanation:The formula for McCabe's cyclomatic complexity is CV=e-n+p+1, where e, n and p denote the number of edges, nodes, and connected components in the control graph, respectively.
Q508.
What does the cyclomatic complexity of a program depict?

a.

The time in man-months required to complete the program

b.

The number of lines of code in the program

c.

The number of decisions in the program

d.

The cost of the program

Discuss
Answer: (c).The number of decisions in the program Explanation:The cyclomatic complexity of a program corresponds to the number of decisions in the program.
Q509.
What is the suggested limit of cyclomatic complexity by McCabe?

a.

5

b.

8

c.

10

d.

12

Discuss
Answer: (c).10 Explanation:McCabe suggests imposing an upper limit of ten for the cyclomatic complexity of a program component.
Q510.
What is the purpose of McCabe's cyclomatic complexity metric during testing?

a.

To determine the optimal size of a module

b.

To estimate the number of errors in a module

c.

To provide a structured testing strategy

d.

To estimate the cost of a piece of software

Discuss
Answer: (c).To provide a structured testing strategy Explanation:Applying McCabe’s cyclomatic complexity leads to a structured testing strategy involving the execution of all linearly-independent paths.
