The Working of for loop by using vb.net with examples and explain its complete working.

The Working of for loop by using vb.net with examples and explain its complete working.

Sub Main()

        Dim a As Integer

        For a = 1 To 10 Step 1

            Console.WriteLine("{0}", a & vbTab)

        Next

        Console.ReadLine()

    End Sub

Working of above program

In  above program FOR loop is used and this loop start from  1 and end at 10 we declare a variable (a) and assign 1 value to this variable when program is compiled and the working of loop is start loop is start from 1 and add 1 by using (step 1) this means 1 add to the value of a=1 when 1 is add to variable (a) then its value become a=2 in the same way  using for loop the output display counting from 1 to 10

Working of while loop with example in vb.net

Sub Main()

        Dim x As Integer

        x = 10

        While x > 5

            Console.WriteLine("{0}", x & vbTab)

            x = x - 1

        End While

      Con  sole.ReadKey()

    End Sub

Working of while loop by using  vb.et

  Sub Main()

        Dim x As Integer

        x =

1

    

    While x <= 49

            Console.WriteLine("{0}", x & vbTab)

            x = x + 1

        End While

        Console.ReadKey()

    End Sub

Working of above program

In  above program while loop is used and this loop start from  1 and end at 49 we declare a variable (a) and assign 1 value to this variable when program is compiled and the working of loop is start loop is start from 1 and add 1 by using (step 1) this means 1 add to the value of a=1 when 1 is add to variable (a) then its value become a=2 in the same way  using for loop the output display counting from 1 to 49

How we find even number by using for loop in vb.net

Sub Main()

        Dim a As Integer

        For a = 20 To 1 Step -2

            Console.WriteLine("{0}", a & vbTab)

        Next

        Console.ReadLine()

    End Sub

Working of above program

In  above program FOR loop is used and this loop start from  20 and end at 0 we declare a variable (a) and assign a=20 value to this variable when program is compiled and the working of loop is start loop is start from  20 and subtract 2 by using (step -2) this means  2 subtract t0 the value of a=20 when 2 is subtract  to variable (a) then its value become a=18 in the same way  using for loop the output display counting from 20 to 2 and display all the even number between the 0 to 20

 How nested loop is work in vb.net with example

Sub Main()

        Dim i, j As Integer

        For i = 1 To 5

            For j = 1 To i

                Console.WriteLine("{0}", i & vbTab)

            Next

        Next

        Console.ReadLine(

)

   

End Sub

How we convert do while loop to while loop

Sub Main()

        Dim a As Integer

        a = 0

        While a < 10

            Console.WriteLine("{0}", a & vbTab)

            a = a + 1

        End While

        Console.ReadLine()

    End Sub

Working of above program

In  above program FOR loop is used and this loop start from  0 and end at 10 we declare a variable (a) and assign 0 value to this variable when program is compiled and the working of loop is start loop is start from 0 and add 1 by using (step 1) this means 1 add to the value of a=1 when 1 is add to variable (a) then its value become a=1  the statement a=a+1 show that 1 is add into a and this value is assign to variable (a) in the same way  using for loop the output display counting from 0 to 9
