Yes, cloud computing refers to the delivery of computing services over the internet.
Cloud computing allows users to access data and applications from anywhere with an internet connection.
It offers scalability, flexibility, and cost-effectiveness compared to traditional on-premises computing.
Examples of cloud computing services include Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
Q17. What is new in C# 10
C# 10 introduces new features like file-scoped namespaces, global using directives, and interpolated string handlers.
File-scoped namespaces allow defining namespaces at the file level instead of wrapping everything in a namespace block.
Global using directives simplify the process of importing namespaces across the entire project.
Interpolated string handlers provide a way to customize how interpolated strings are processed.
Q18. What is oops concepts
OOPs concepts are the principles of Object-Oriented Programming that help in designing and implementing software systems.
Encapsulation - bundling of data and methods that operate on that data
Inheritance - ability of a class to inherit properties and methods from its parent class
Polymorphism - ability of objects to take on multiple forms or behaviors
Abstraction - hiding of complex implementation details and showing only the necessary information
Examples: Java, C++, Python, Rub...read more
Q19. write program for finding duplicates
Program to find duplicates in an array of strings
Iterate through the array and store each element in a hash set
If an element is already in the hash set, it is a duplicate
Return a list of all duplicates found
Q20. Implementation of OOPS
OOPS (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
OOPS focuses on the use of classes and objects to organize code and data
Encapsulation, inheritance, polymorphism, and abstraction are key principles of OOPS
Example: Inheritance allows a class to inherit properties and methods from another class
Q21. Design Patterns in C#
Design patterns in C# are reusable solutions to common problems in software design.
Design patterns help in creating maintainable and scalable code.
Some common design patterns in C# include Singleton, Factory, Observer, and Strategy.
Each design pattern has its own purpose and can be applied in different scenarios.
Design patterns promote code reusability and improve code organization.
Q22. Write basic code
Basic code example using an array of strings
Declare an array of strings in the preferred programming language
Initialize the array with some string values
Access and manipulate elements in the array as needed
Q23. Write simple profram
A simple program to print 'Hello, World!'
Create a new file with a .py extension
Write 'print('Hello, World!')' inside the file
Save the file and run it using a Python interpreter
Q24. Oops concept in C#
Oops concept in C# refers to Object-Oriented Programming principles like Inheritance, Polymorphism, Encapsulation, and Abstraction.
Inheritance allows a class to inherit properties and behavior from another class.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
Encapsulation hides the internal state of an object and only exposes necessary functionalities.
Abstraction focuses on the essential features of an object while hiding unne...read more
Q25. Explain oops concept
OOPs (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
OOPs focuses on creating objects that interact with each other to solve a problem
Key principles include Inheritance, Encapsulation, Polymorphism, and Abstraction
Inheritance allows a class to inherit properties and behavior from another class
Encapsulation hides the internal state of an object and only exposes necessary functionality
Polymorphism allows o...read more
