SoftDev Ch5 Test Revision

In which stage of the problem-solving methodology is internal documentation completed?

• Analysis

• Design

• Development

• Evaluation

Evaluation checks that

• the solution is efficient

• the solution is cost-effective

• the solution is easy to use

• the solution satisfies the needs of the user.

Data structures can take several forms. A record is different to an array because the elements

• must be the same data type

• can have different data types

• are always numbers

• are always strings

What is the primary focus of user-centred design in software development?

• Reducing development costs

• Prioritising the needs, preferences and behaviours of end users

• Maximising profit

• Minimising code errors

The role of personas in user-centred design is to

• increase the number of users

• reduce development time

• optimise the UI for speed and performance

• ensure data security

A programmer chooses a record over an array for data storage to

• store only numbers

• store diverse data types within a single structure

• store only strings

• store only one type of data

What will be the output of the following pseudocode? x ← 7 y ← 12 IF x > y THEN output = x + y ELSE output = y - x END IF DISPLAY output

• A. 19

• B. 84

• C. 0

• D. 5

What will be the output of the following pseudocode? x ← 10 y ← 3 result ← (x % y == 1) AND (x // y > 2) DISPLAY result

• True

• False

Which of the following statements best describes the relationship between a class and an object?

• An object is a blueprint for creating classes

• A class and an object are the same thing

• A class is a blueprint for creating objects and each object can have different attribute values.

• An object cannot have attributes

You would use protected visibility for a class variable when the variable should be

• accessed by any class

• accessed only by the class and its subclasses.

• accessed only by the class

• accessed by all classes in the package
