1.
Which of these is not covered in the OOPs quiz test?
Correct Answer
D. None of the above
Explanation
The correct answer is "None of the above". This means that all of the options mentioned (Object, Encapsulation, and Inheritance) are covered in the OOPs quiz test.
2.
What is the purpose of the C# .NET OOPs test?
Correct Answer
B. To assess candidate’s knowledge of Object-Oriented Programming concepts
Explanation
The purpose of the C# .NET OOPs test is to assess a candidate's knowledge of Object-Oriented Programming concepts. It is used as a tool for evaluating the candidate's understanding and proficiency in this area, particularly in the context of C# .NET development. This test helps employers determine if the candidate has the necessary skills and expertise required for the job.
3.
OOP is a programming model used to organize the programs around objects and data rather than action and logic.
Correct Answer
A. True
Explanation
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.
4.
The test contains which of the following
Correct Answer
D. All of the above
Explanation
The correct answer is "All of the above" because the question is asking about the contents of the test, and all the options listed (Multiple Choice Questions, Fill in the Blank, True or False) are different types of questions that could be included in the test. Therefore, the correct answer is that the test contains all of these question types.
5.
What is the duration of the test?
Correct Answer
B. 20 minutes
Explanation
The correct answer is 20 minutes. This means that the duration of the test is 20 minutes.
6.
Encapsulation is part of the C# .NET OOPs Quiz Test
Correct Answer
B. True
Explanation
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.
7.
What is the total number of questions?
Correct Answer
D. 20
Explanation
The correct answer is 20. This is because the question is asking for the total number of questions, and out of the given options, 20 is the only number that represents a possible total number of questions.
8.
Does C# support multiple inheritance?
Correct Answer
B. No
Explanation
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.
9.
What is the top .NET class that everything is derived from?
Correct Answer
C. System. Object
Explanation
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.
10.
Which .NET collection class allows elements to be accessed using a unique key?
Correct Answer
D. Hashtable
Explanation
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.
