Exit statement and Continue statement


Exit statement

Module loops
   Sub Main()
      ' local variable definition
      Dim a As Integer = 10
      ' while loop execution '
      While (a < 20)
          Console.WriteLine("value of a: {0}", a)
          a = a + 1
          If (a > 15) Then
              'terminate the loop using exit statement
              Exit While
          End If
      End While
      Console.ReadLine()
   End Sub
End Module

When the above code is compiled and executed, it produces the following result:
value of a: 10
value of a: 11
value of a: 12
value of a: 13
value of a: 14
value of a: 15

Continue statement

Module loops
   Sub Main()
      ' local variable definition 
      Dim a As Integer = 10
      Do
          If (a = 15) Then
              ' skip the iteration '
              a = a + 1
              Continue Do
          End If
          Console.WriteLine("value of a: {0}", a)
          a = a + 1
      Loop While (a < 20)
      Console.ReadLine()
   End Sub
End Module

When the above code is compiled and executed, it produces the following result:
value of a: 10
value of a: 11
value of a: 12
value of a: 13
value of a: 14
value of a: 16
value of a: 17
value of a: 18
value of a: 19
