Switch Statement in C#

Switch Statement in C#:-


It is used to create a choice-based or option-based program, It provides multiple case statements to represent multiple-choice, we can select a particular statement under switch then it will match from respective case statements.


switch(option)
{

   case option-value:
     Statement;
     break;
   case option-value:
     Statement;
     break;
    case option-value:
     Statement;
     break;
    default:
     Statement;
     break;

}


We will check option==optionvalue then that statement will be executed.


class SwitchProgram
    {
        static void Main()
        {
            char ch;
            Console.WriteLine("Enter Char");
            ch = char.Parse(Console.ReadLine());
            switch (ch)
            {
                case 'a':
                case 'e':
                case 'i':
                case 'o':
                case 'u':
                Console.WriteLine("Vowel");
                break;
                default:
                Console.WriteLine("Consonent");
                break;


            }
            Console.ReadKey();
           
        }

    }

    Console.WriteLine("Enter Second Number : ");
    b =int.Parse(Console.ReadLine());
    switch(a>b)
    {
    case true:
    Console.WriteLine("1st number is greater and value is {0}",a);

    #Shiva Patel
    Ans3:- Leap Year using Switch

    int y;
    Console.WriteLine("Enter Year : ");
    y = int.Parse((Console.ReadLine()));
    switch (y%400==0 || y%4==0 && y%100!=0)
    {
    case true:
    Console.WriteLine("Leap Year");
    break;
    default:
    Console.WriteLine("{0} Not a Leap Year",y);

DSA in C# | Data Structure and Algorithm using C#

  DSA in C# |  Data Structure and Algorithm using C#: Lecture 1: Introduction to Data Structures and Algorithms (1 Hour) 1.1 What are Data Structures? Data Structures are ways to store and organize data so it can be used efficiently. Think of data structures as containers that hold data in a specific format. Types of Data Structures: Primitive Data Structures : These are basic structures built into the language. Example: int , float , char , bool in C#. Example : csharp int age = 25;  // 'age' stores an integer value. bool isStudent = true;  // 'isStudent' stores a boolean value. Non-Primitive Data Structures : These are more complex and are built using primitive types. They are divided into: Linear : Arrays, Lists, Queues, Stacks (data is arranged in a sequence). Non-Linear : Trees, Graphs (data is connected in more complex ways). Example : // Array is a simple linear data structure int[] number...

JSP Page design using Internal CSS

  JSP is used to design the user interface of an application, CSS is used to provide set of properties. Jsp provide proper page template to create user interface of dynamic web application. We can write CSS using three different ways 1)  inline CSS:-   we will write CSS tag under HTML elements <div style="width:200px; height:100px; background-color:green;"></div> 2)  Internal CSS:-  we will write CSS under <style> block. <style type="text/css"> #abc { width:200px;  height:100px;  background-color:green; } </style> <div id="abc"></div> 3) External CSS:-  we will write CSS to create a separate file and link it into HTML Web pages. create a separate file and named it style.css #abc { width:200px;  height:100px;  background-color:green; } go into Jsp page and link style.css <link href="style.css"  type="text/css" rel="stylesheet"   /> <div id="abc"> </div> Exam...

Uncontrolled form input in React-JS

  Uncontrolled form input in React-JS? If we want to take input from users without any separate event handling then we can uncontrolled the data binding technique. The uncontrolled input is similar to the traditional HTML form inputs. The DOM itself handles the form data. Here, the HTML elements maintain their own state that will be updated when the input value changes. To write an uncontrolled component, you need to use a ref to get form values from the DOM. In other words, there is no need to write an event handler for every state update. You can use a ref to access the input field value of the form from the DOM. Example of Uncontrolled Form Input:- import React from "react" ; export class Info extends React . Component {     constructor ( props )     {         super ( props );         this . fun = this . fun . bind ( this ); //event method binding         this . input = React . createRef ();...
