Which of the following is NOT true about a class in object-oriented programming? 1. It is a blueprint for creating objects, 2. It can have multiple instances, 3. It can have both attributes and behaviors, 4. It is an object itself. 2. Which keyword is used to define a class in most programming languages? a. class, b. object, c. struct, d. def. 3. Which of the following is NOT a common visibility modifier for class members? a. private, b. public, c. protected, d. local. 4. Which of the following is NOT a benefit of using classes in object-oriented programming? a. Code reusability, b. Data encapsulation, c. Code obfuscation, d. Modularity. 5. What represents the state or characteristics of an object? a. Fields, b. Methods, c. Structure, d. Object-status.
Understand the Problem
The question is a multiple-choice quiz about concepts related to object-oriented programming. It tests knowledge on classes, keywords used to define classes, visibility modifiers, benefits of using classes, and the representation of an object's state.
Answer
1. A class is NOT an object itself. 2. 'class' keyword defines a class. 3. 'Local' is not a visibility modifier. 4. Code obfuscation is not a benefit. 5. Fields represent object characteristics.
- The statement 'It is an object itself' is NOT true about a class. 2. The keyword 'class' is used to define a class. 3. 'Local' is NOT a common visibility modifier. 4. 'Code obfuscation' is NOT a benefit. 5. 'Fields' represent the state or characteristics of an object.
Answer for screen readers
- The statement 'It is an object itself' is NOT true about a class. 2. The keyword 'class' is used to define a class. 3. 'Local' is NOT a common visibility modifier. 4. 'Code obfuscation' is NOT a benefit. 5. 'Fields' represent the state or characteristics of an object.
More Information
In object-oriented programming, a class is a blueprint and not an object itself. The keyword 'class' is typically used across many languages to define classes. Common visibility modifiers include 'public,' 'private,' and 'protected,' while 'local' is incorrect. The main benefits of classes are modularity, reusability, and encapsulation.
Tips
A common mistake is confusing a class with an object. Remember that a class is a template from which objects are instantiated.
