5. • The For loop is the most popular loop.
•For loops enable us to execute a series of expressions
multiple numbers of times.
•Syntax:
For index=start to end[Step step]
[statements]
[Exit For]
[statements]
Next[index]

6. Example:
Module Module1
Sub Main()
Dim d As Integer
For d = 0 To 2
System.Console.WriteLine("In the For Loop")
Next d
End Sub
End Module

7. •While loop keeps executing until the
condition against which it tests remain true.
•Syntax:
While condition
[statements]
End While

8. Example:
Module Module1
Sub Main()
Dim d, e As Integer
d=0
e=6
While e > 4
e -= 1
d += 1
End While
System.Console.WriteLine("The Loop ran " & e &
"times")
End Sub
End Module By: Abhishek Pachisia

9. •The Do loop keeps executing it's statements while or until the
condition is true.
•Two keywords, while and until can be used with the do loop.
•The Do loop also supports an Exit Do statement which makes
the loop to exit at any moment.
•Syntax:
Do[{while | Until} condition]
[statements]
[Exit Do]
[statements]
Loop
