OOP is a programming model used to organize the programs around objects and data rather than action and logic.
- A.
True
- B.
False
- C.
No idea
- D.
Uncertain
Correct Answer
A. TrueExplanation
OOP, or Object-Oriented Programming, is indeed a programming model that focuses on organizing programs around objects and data. In this approach, objects are created from classes, which act as blueprints for the objects. These objects can contain both data (attributes) and behavior (methods), allowing for a more modular and structured way of designing and implementing software. Therefore, the statement "OOP is a programming model used to organize the programs around objects and data rather than action and logic" is true.Rate this question:

Encapsulation is part of the C# .NET OOPs Quiz Test
- A.
False
- B.
True
- C.
No idea
- D.
None of the above
Correct Answer
B. TrueExplanation
Encapsulation is indeed a fundamental concept in object-oriented programming, including C# .NET. It refers to the bundling of data and methods within a class, allowing access to the data only through the defined methods. This helps in achieving data hiding, abstraction, and protection, as the internal details of the class are hidden from the outside world. By marking the answer as "True," it indicates that encapsulation is indeed a part of the C# .NET OOPs Quiz Test.Rate this question:

Does C# support multiple inheritance?
- A.
Yes
- B.
No
- C.
No idea
- D.
None of the above
Correct Answer
B. NoExplanation
C# does not support multiple inheritance. In C#, a class can only inherit from one base class. This is because multiple inheritance can lead to conflicts and ambiguity in the code. To overcome this limitation, C# supports the concept of interfaces, which allow a class to inherit from multiple interfaces but not multiple classes.Rate this question:

What is the top .NET class that everything is derived from?
- A.
Object
- B.
System.Net
- C.
System. Object
- D.
System. Root
Correct Answer
C. System. ObjectExplanation
The correct answer is System.Object. In the .NET framework, all classes are derived from the System.Object class. This class provides the basic functionality and behavior that is common to all objects in the framework. It defines methods such as ToString(), Equals(), and GetHashCode(), which can be overridden by derived classes. By having all classes derive from System.Object, it allows for a unified approach to working with objects in the .NET framework.Rate this question:

Which .NET collection class allows elements to be accessed using a unique key?
- A.
ListDictionary
- B.
Stack
- C.
ArrayList
- D.
Hashtable
Correct Answer
D. HashtableExplanation
The correct answer is Hashtable. Hashtable is a collection class in .NET that allows elements to be accessed using a unique key. It stores key-value pairs and provides fast access to elements based on their keys. The keys in a Hashtable must be unique, and they are used to retrieve the corresponding values. Hashtable uses a hash function to map keys to their corresponding positions in the internal data structure, which allows for efficient retrieval of elements.Rate this question:
