Q81.
What is required for a successful software comprehension process?

a.

Knowledge about programming

b.

Knowledge about the application domain

c.

Well-structured programs and proper documentation

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The software comprehension process requires knowledge about programming, knowledge about the application domain, well-structured programs, and proper documentation.
Q82.
How does the reader's existing knowledge affect the software comprehension process?

a.

The more knowledge the reader has, the less effective the process will be

b.

The better the source code maps onto the reader's existing knowledge, the more effective the process will be

c.

The reader's existing knowledge has no effect on the software comprehension process

d.

The reader's existing knowledge only helps with understanding well-structured programs and proper documentation

Discuss
Answer: (b).The better the source code maps onto the reader's existing knowledge, the more effective the process will be Explanation:The better the source code maps onto the reader's existing knowledge, the more effective the software comprehension process will be.
Q83.
How does the structure of a program impact the understanding of the program text?

a.

If the structure of a program shows no relation with the structure of the application domain, understanding of the program text is seriously hampered.

b.

If application domain concepts map onto well-delineated program units, then the program text will be easily understood.

c.

Proper documentation is the only factor that affects the understanding of the program text

d.

The structure of a program has no effect on the understanding of the program text

Discuss
Answer: (b).If application domain concepts map onto well-delineated program units, then the program text will be easily understood. Explanation:If the structure of a program shows no relation with the structure of the application domain, or the reader cannot discern this structure, then understanding of the program text is seriously hampered. If application domain concepts map onto well-delineated program units, then the program text will be more easily understood.
Q84.
Which strategy is typically used by inexperienced programmers for studying program text?

a.

Local strategy

b.

Top-down strategy

c.

As-needed strategy

d.

Systematic strategy

Discuss
Answer: (c).As-needed strategy Explanation:Inexperienced programmers tend to use the as-needed strategy for studying program text.
Q85.
What does the systematic strategy offer in comparison to the as-needed strategy for studying program text?

a.

A better insight into local information

b.

An overall understanding of the system

c.

A better understanding of the causal relationships between program components

d.

None of the above

Discuss
Answer: (c).A better understanding of the causal relationships between program components Explanation:The systematic strategy gives a better insight into causal relations between program components, which is not offered by the as-needed strategy.
Q86.
What are delocalized plans in the context of program text?

a.

Conceptually related pieces of code located in program parts that are physically close together

b.

Conceptually related pieces of code located in program parts that are physically wide apart

c.

Locally correct changes that lead to new problems at different, unforeseen places

d.

None of the above

Discuss
Answer: (b).Conceptually related pieces of code located in program parts that are physically wide apart Explanation:Delocalized plans are defined as conceptually related pieces of code located in program parts that are physically wide apart.
Q87.
What is the effect of excessive use of inheritance on the comprehension process of a program text?

a.

It reduces the use of delocalized plans

b.

It improves the understanding of the program text

c.

It increases the use of delocalized plans

d.

None of the above

Discuss
Answer: (c).It increases the use of delocalized plans Explanation:Excessive use of inheritance increases the use of delocalized plans, which can seriously hamper maintenance activities.
Q88.
What is the effect of using the as-needed strategy on the implementation of changes to the program text?

a.

It reduces the probability of ripple effects

b.

It increases the probability of ripple effects

c.

It has no effect on the implementation of changes

d.

None of the above

Discuss
Answer: (b).It increases the probability of ripple effects Explanation:The as-needed strategy increases the probability of ripple effects, i.e. changes that are locally correct but lead to new problems at different, unforeseen places.
Q89.
What is the systematic strategy for studying program text?

a.

Reading the program text from beginning to end like a piece of prose

b.

Forming an overall understanding of the system through a systematic top-down study

c.

Forming an overall understanding of the system through a bottom-up approach

d.

Forming an understanding of the system by only focusing on local information

Discuss
Answer: (b).Forming an overall understanding of the system through a systematic top-down study Explanation:The systematic strategy for studying program text involves forming an overall understanding of the system through a systematic top-down study of the program text.
Q90.
What is the as-needed strategy for studying program text?

a.

Forming an overall understanding of the system through a systematic top-down study

b.

Reading the program text from beginning to end like a piece of prose

c.

Forming an understanding of the system by only focusing on local information

d.

Forming an overall understanding of the system through a bottom-up approach

Discuss
Answer: (b).Reading the program text from beginning to end like a piece of prose Explanation:The as-needed strategy for studying program text involves reading the program text from beginning to end like a piece of prose and formulating hypotheses on the basis of local information.
