Looping Statements in c#

Looping Statements:

                1) for loop

                2) while loop

                3) do while loop

                4) for each loo

Syntax for for  loop:

                using System;

                class ForLoopTest

                {              static void Main()

                 { 

                for (int i = 1; i <= 5; i++)

                 {

                 Console.WriteLine(i);   }  }  }

      

Output:

1

2

3

4

5

Syntax for while loop:

While ()

{

Statements

[increment/decrement]

} 

Example:

using System;

class WhileTest

{      static void Main()

    {

        int n = 1

while (n < 6)                                      

        {               Console.WriteLine("Current value of n is {0}", n);

            n++;

        }   }   }

   

Syntax fro do:

do

{   Statements

[increment/decrement]

} while condition

Example:

using System;

public class TestDoWhile

{      public static void Main ()

    {           int x = 0;

        do

        {             Console.WriteLine(x);

            x++;

        } while (x < 5);   }   }

Syntax for for each loop:

The foreach statement repeats a group of embedded statements for each element in an a rray or an object collection.

Foreach(datatype variable in array/list collection name)

{   Statement

}

Example

class ForEachTest

{   

    static void Main(string[] args)

    {           int[] fibarray = new int[] { 0, 1, 2, 3, 5, 8, 13 };

        foreach (int i in fibarray)

        {

            System.Console.WriteLine(i);

        }

    }

}
