Q511.
What do complexity metrics like those of Halstead and McCabe measure?

a.

The number of decisions in a program

b.

The time in man-months required to complete the program

c.

The size of the task to be accomplished

d.

The cost of a piece of software

Discuss
Answer: (c).The size of the task to be accomplished Explanation:Complexity metrics like those of Halstead, McCabe, and others measure attributes which are in some sense related to the size of the task to be accomplished.
Q512.
What is the purpose of complexity metrics like McCabe's, Halstead's and others?

a.

To determine the size of a module

b.

To estimate the number of errors in a module

c.

To estimate the cost of software

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Complexity metrics like McCabe's and Halstead's serve various purposes such as determining the optimal size of a module, estimating the number of errors in a module, or estimating the cost of software.
Q513.
What is the problem with the known complexity metrics?

a.

They are not context-sensitive

b.

They only measure a few facets

c.

Both a and b

d.

Neither a nor b

Discuss
Answer: (c).Both a and b Explanation:The known complexity metrics are not very context-sensitive and only measure a few facets, which makes them insufficient.
Q514.
What is the 'representation condition' In terms of measurement theory?

a.

The condition that the numerical relations should be preserved in the empirical relations system

b.

The condition that the complexity metric should be such that FA>FB

c.

The condition that the complexity yardsticks should be used with care

d.

None of the above

Discuss
Answer: (a).The condition that the numerical relations should be preserved in the empirical relations system Explanation:The representation condition as the condition that the numerical relations should be preserved in the empirical relations system.
Q515.
Can a higher value of complexity metric necessarily mean that a program is more complex?

a.

Yes

b.

No

c.

May be Yes or No

d.

Can't say

Discuss
Answer: (b).No Explanation:A more complex program does not necessarily result in a higher value for a complexity metric, as complexity is made up of many specific attributes.
Q516.
What is the recommendation for the use of complexity metrics?

a.

Use a single metric

b.

Use multiple metrics

c.

Do not use complexity metrics

d.

Use complexity metrics with caution

Discuss
Answer: (b).Use multiple metrics Explanation:The use of multiple metrics is likely to yield better insights into complexity, but the results must still be interpreted with care.
Q517.
What do validations of software science and cyclomatic complexity indicate?

a.

They are better indicators of coding effort, maintainability, and reliability than the length of a program.

b.

They are not substantially better indicators of coding effort, maintainability, and reliability than the length of a program.

c.

They are not valid indicators of coding effort, maintainability, and reliability.

d.

They are better indicators of coding effort, maintainability, and reliability only for small programs.

Discuss
Answer: (b).They are not substantially better indicators of coding effort, maintainability, and reliability than the length of a program. Explanation:Validations of both software science and cyclomatic complexity indicate that they are not substantially better indicators of coding effort, maintainability, or reliability than the length of a program.
Q518.
Why is the length of a program (number of lines of code) often used as an indicator of complexity?

a.

It is the only metric that is easy to determine.

b.

It has a high correlation with control-related complexity metrics such as McCabe's cyclomatic complexity.

c.

It takes into account the density of if-statements in a program.

d.

It is the only complexity metric that has been validated.

Discuss
Answer: (a).It is the only metric that is easy to determine. Explanation:The latter (length of program) is much easier to determine, though.
Q519.
What does the graph depict in the design process of a set of modules and their mutual dependencies?

a.

Nodes of the graph correspond to modules and the edges denote the information flow between modules

b.

Nodes of the graph correspond to modules and the edges denote the type of dependencies between modules

c.

Nodes of the graph correspond to modules and the edges denote the amount of knowledge between modules

d.

Nodes of the graph correspond to modules and the edges denote the complexity of the relations between modules

Discuss
Answer: (b).Nodes of the graph correspond to modules and the edges denote the type of dependencies between modules Explanation:The nodes of the graph correspond to modules and the edges denote the type of dependencies between modules, such as module A contains module B, module A follows module B, etc.
Q520.
What is the purpose of knowing the intermodule relations in a design process?

a.

To assess the amount of knowledge between modules

b.

To assess the information flow between modules

c.

To assess the complexity of the relations between modules

d.

To assess the amount of procedure calls between modules

Discuss
Answer: (c).To assess the complexity of the relations between modules Explanation:It is important to know the intermodule relations in a design process to assess the complexity of the relations between modules. The amount of knowledge between modules should be kept to a minimum.
