Which feature is exclusive to Object-Oriented languages compared to Object-Based and Class-Based languages?

Inheritance for specialization between classes.

How do software construction activities enhance software quality?

Unit testing ensures functionality; planning supports maintainability.

What is the primary purpose of a meta-model as shown in the diagram?

To establish the elements, relationships, and modeling rules for modeling.

Which statement best explains the relationship between data and methods in an object-oriented system?

Methods manipulate data, potentially changing the object's state.

What is the purpose of code refactoring?

Refactoring improves code design without changing its behavior.

What is an abstract data type (ADT)?

A precisely specified data type, independent of implementation.

Which of the following statements best describes the role of reverse engineering in dealing with legacy code?

It analyzes legacy code to extract useful info and make modifications.

What are differentiates abstract objects (AO) from software objects (SO) in modeling?

AO represent concepts, while SO represent programming entities.

What are differentiates approaches used by the Functional and Logical programming?

Functional uses recursion, while Logic programming uses logical rules.

Which of the following best describes the role of assertions in programming?

Assertions help ensure variable states and improve code readability.

1
Which feature is exclusive to Object-Oriented languages compared to Object-Based and Class-Based languages?
Representation of real-world entities.
Objects with encapsulated data.
Inheritance for specialization between classes.
Classes that organize object types.
2
How do software construction activities enhance software quality?
Coding is the sole factor for quality improvement.
Unit testing ensures functionality; planning supports maintainability.
Software quality remains unaffected by construction activities.
Implementation modeling only affects debugging, not design quality.
3
What is the primary purpose of a meta-model as shown in the diagram?
To define the behavior of a system.
To establish the elements, relationships, and modeling rules for modeling.
To execute system functions.
To represent real-world entities directly.
4
Which statement best explains the relationship between data and methods in an object-oriented system?
Methods are static and cannot alter the object’s data.
Data defines the object’s type, while methods only store information.
Data and methods are unrelated in object-oriented systems.
Methods manipulate data, potentially changing the object's state.
5
What is the purpose of code refactoring?
Refactoring improves code design without changing its behavior.
Refactoring alters the behavior of the code for optimization.
Refactoring converts code into a different programming language.
Refactoring adds new functionality to the existing code.
6
What is an abstract data type (ADT)?
A data type defined by specific implementation details.
A data type that represents concrete entities directly.
A precisely specified data type, independent of implementation.
A set of data values with partial implementation.
7
Which of the following statements best describes the role of reverse engineering in dealing with legacy code?
It analyzes legacy code to extract useful info and make modifications.
It converts legacy code directly into a new programming language.
It is used to create new software without examining old code.
It relies on manual coding to replace outdated software components.
8
What are differentiates abstract objects (AO) from software objects (SO) in modeling?
AO represent concepts, while SO represent programming entities.
SO describe abstract concepts, while AO define software operations.
AO represent tangible items, while SO are data types.
SO represent real-world entities, while AO model data structures.
9
What are differentiates approaches used by the Functional and Logical programming?
Logic programming uses recursion, while Functional uses iterative loops.
Functional uses recursion, while Logic programming uses logical rules.
Both paradigms use the same method for computing the factorial function.
Functional programming uses loops, while Logic programming uses recursion.
10
Which of the following best describes the role of assertions in programming?
Assertions help ensure variable states and improve code readability.
Assertions slow down program execution and should be avoided.
Assertions only work during runtime error localization.
Assertions cannot be disabled and must always be active.
