The Switch Case Statement In Visual C# .Net

The switch case statement is also used for making decision, unlike the if else statement , we can not test conditions like "greater than" or "less than" . in switch case we can test the value of a variable and decide what to do if a particular value is stored in the variable.

the syntax for switch statement below


switch(varable to test)

{

case value 1 :
statements if value 1 stored in the variable;
break;

case value 2 :
statements if value 2 stored in the variable;
break;

*
*
default:
statements if none of the values match;
break;
}

example

the user will enter a weekday number( 1 to 7 ) and the program will display the name of the corresponding day

How To Make A Simple Console Application In C#

this is a simple program to separate 6 digits from input, first you create string and name it (shim)  and you prompt the user to enter the number using console.write(); then you assign the user to input shim using the console.readline function so on you display each display/character using writeline , in this the argument comes after the comma in this argument

Console.WriteLine("First digit: {0}", shim.Substring(0,1));

shim.Substring(0,1) 

shim.substring(0,1) , when you use susbstring its going to read the string which is , the user input

console.readkey(); will keep the application awake

lets make the application , create a new project and select console application and name it whatever you want , add the codes below

using System;

namespace simple_console_application

{
        class Program

        {
                      static void Main(string[] args)

                {
                        string shim = "";

                        Console.Write("Enter a 6 digit Number: ");

                        shim = Console.ReadLine();

                        Console.WriteLine("First digit: {0}", shim.Substring(0,1));

                        Console.WriteLine("Second digit: {0}", shim.Substring(1, 1));

                        Console.WriteLine("Third digit: {0}", shim.Substring(2,1));

                        Console.WriteLine("Fourth digit: {0}", shim.Substring(3,1));

                        Console.WriteLine("Fifth digit: {0}", shim.Substring(4,1));

                        Console.WriteLine("Sixth digit: {0}", shim.Substring(5, 1));

                        Console.ReadKey();
