Q491.
What are the two classes of software attributes considered in measuring software complexity?

a.

Internal and external attributes

b.

Intra-modular and inter-modular attributes

c.

Design and structure attributes

d.

Size and computational attributes

Discuss
Answer: (b).Intra-modular and inter-modular attributes Explanation:The type of software attributes considered in measuring software complexity can be broadly categorized into two classes: intra-modular attributes which are attributes of individual modules, and inter-modular attributes which are attributes of a system viewed as a collection of modules with dependencies.
Q492.
What is the purpose of measuring software complexity in quantitative terms?

a.

To determine the time needed to solve a problem

b.

To determine the effort needed to construct or change software

c.

To assess the quality of a design or program

d.

To calculate the complexity of the computation performed

Discuss
Answer: (c).To assess the quality of a design or program Explanation:The purpose of measuring software complexity in quantitative terms is to assess the quality of a design or program, to guide reengineering efforts, etc.
Q493.
What is a size-based complexity metric?

a.

A metric that measures the structure of a piece of software

b.

A metric that measures the time needed to solve a problem

c.

A metric that measures the effort needed to develop a piece of software

d.

A metric that measures the complexity of the computation performed

Discuss
Answer: (c).A metric that measures the effort needed to develop a piece of software Explanation:Size-based complexity metrics measure the size of a piece of software such as the number of lines of code, and it gives a fair indication of the effort needed to develop that piece of software.
Q494.
What is a structure-based complexity metric?

a.

A metric that measures the size of a piece of software

b.

A metric that measures the time needed to solve a problem

c.

A metric that measures the effort needed to develop a piece of software

d.

A metric that measures the design quality of a piece of software

Discuss
Answer: (d).A metric that measures the design quality of a piece of software Explanation:Structure-based complexity metrics measure the structure of a piece of software and is a good indicator of its design quality because a program that has a complicated control structure or uses complicated data structures is likely to be difficult to comprehend and maintain, and thus more complex.
Q495.
What is the easiest way to measure software size?

a.

Using Halstead's method

b.

By counting the number of elements per module

c.

By using a prettyprinter

d.

By counting the number of lines of code

Discuss
Answer: (d).By counting the number of lines of code Explanation:The easiest way to measure software size is to count the number of lines of code.
Q496.
What is the ideal size of a module according to (Weinberg, 1971)?

a.

7 elements

b.

30 lines of code

c.

More than 7 elements

d.

Unlimited capacity

Discuss
Answer: (b).30 lines of code Explanation:In (Weinberg, 1971), for instance, the ideal size of a module is said to be 30 lines of code.
Q497.
Why is a module suggested to contain at most 7 elements?

a.

It is easier to understand

b.

There is a more permanent memory of almost unlimited capacity

c.

To counteract the effects of verbose programming

d.

Based on research in psychology that suggests human memory has a short-term memory of about seven slots

Discuss
Answer: (d).Based on research in psychology that suggests human memory has a short-term memory of about seven slots Explanation:This number seven can be traced back to research in psychology, which suggests that human memory is hierarchically organized with a short-term memory of about seven slots, while there is a more permanent memory of almost unlimited capacity.
Q498.
What is the main problem associated with using the number of lines of code as a complexity metric?

a.

It makes it hard to compare programs written in different languages

b.

Some lines are more complex than others

c.

Different programmers write verbose programs

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:There are serious objections to the direct use of the number of lines of code as a complexity metric. Some programmers write more verbose programs than others. We should at least normalize the counting to counteract these effects and be able to compare different pieces of software. This can be achieved by using a prettyprinter, a piece of software that reproduces programs in a given language in a uniform way. A second objection is that this technique makes it hard to compare programs written in different languages. If the same problem is solved in different languages, the results may differ considerably in length.
Q499.
What does Halstead's method, also known as 'software science', use to overcome the problems associated with metrics based on a direct count of lines of code?

a.

The number of unique operands in the program

b.

The number of unique operators and operands in the program

c.

The number of elements per module

d.

The number of lines of code

Discuss
Answer: (b).The number of unique operators and operands in the program Explanation:Halstead’s method, also known as ‘software science’, uses a refinement of counting lines of code. This refinement is meant to overcome the problems associated with metrics based on a direct count of lines of code. Halstead’s method uses the number of operators and operands in a piece of software.
Q500.
Why is the number seven used as a limit for the number of elements per module?

a.

It's a research finding from psychology

b.

It's a universally accepted standard

c.

It's the number of unique operators in the program

d.

It's the number of unique operands in the program

Discuss
Answer: (a).It's a research finding from psychology Explanation:The number seven can be traced back to research in psychology, which suggests that human memory has a short-term memory of about seven slots.
