Chapter 1 : Introduction of OOP

1.      What is the main focus of Object-Oriented Analysis (OOA)?

• A. Developing hardware systems for problem-solving

• B. Writing code before analyzing the problem domain

• C. Finding and describing objects or concepts in the problem domain

• D. Focusing only on the user interface

2.      Which of the following best describes a "class"?

• A. A method that performs actions on objects

• B. A blueprint or prototype that defines attributes and methods for objects

• C. A single instance of data in the system

• D. A type of software tool used for debugging

3.      Which principle of OOP is demonstrated when a subclass inherits attributes and methods from a parent class?

• A. Encapsulation

• B. Abstraction

• C. Polymorphism

• D. Inheritance

4.      In OOP, encapsulation ensures:

• A. Data security by hiding internal object details

• B. The ability for objects to perform multiple tasks

• C. The reuse of code across different applications

• D. The creation of new methods automatically

5.      Polymorphism allows:

• A. Objects to inherit attributes from their parent class

• B. Objects to communicate using messages

• C. One interface to be implemented in multiple ways

• D. The hiding of internal details of a class

6.      Which of the following is NOT an advantage of OOP?

• A. Easier debugging

• B. Reusability of code

• C. Faster hardware execution speed

• D. Closely reflects real-world systems

7.      What differentiates Object-Oriented Programming from Structured Programming?

• A. Use of global variables

• B. Division of programs into functions and modules

• C. Grouping of data and operations into objects

• D. Lack of message-passing mechanisms
