.NET & C# Basics

Which of the following best describes object-oriented programming (OOP)?

• A type of programming that focuses on functions

• A programming paradigm that focuses on objects containing attributes and methods

• A method to perform mathematical calculations

• A programming style that does not involve classes

What are attributes in object-oriented programming?

• Methods used to perform tasks

• Variables that describe the state of an object

• Functions that process data

• Commands to execute the program

What is the process of creating an object from a class called?

• Inheritance

• Encapsulation

• Instantiation

• Abstraction

What does the concept of "inheritance" allow in object-oriented programming?

• Reusing code by creating new classes based on existing ones

• Hiding the attributes and methods of an object

• Sending messages to other objects

• Dividing a program into functions

Which of the following is an example of a method in a class?

• An object's color

• A car's ability to accelerate

• The size of a database

• A computer's memory capacity

What is the Unified Modeling Language (UML) used for?

• Writing C# code

• Communicating the results of object-oriented analysis and design

• Managing memory in C#

• Debugging object-oriented programs

What is the purpose of encapsulation in object-oriented programming?

• To modify the behavior of objects

• To wrap attributes and methods inside an object and hide implementation details

• To simplify variable declarations

• To create new classes based on existing ones

Which of the following languages is C# most closely related to in terms of syntax and features?

• Ruby

• Java

• PHP

What is the purpose of the .NET Framework in C#?

• To manage file systems on a server

• To execute applications and provide a class library for developers

• To compile Java programs

• To provide an alternative to event-driven programming

What is the role of the Common Language Runtime (CLR) in the .NET Framework?

• It converts Java code into machine instructions

• It executes .NET programs and provides functionality like memory management and error handling

• It is used to write SQL queries

• It stores the source code of C# applications
