I'm trying to write code to show data from two arrays via a MsgBox(). I have the code below, but of course it doesn't work:

```
Dim numbers() As Integer = {1, 4, 7}
Dim letters() As String = {"a", "b", "c"}
' Iterate through the list by using nested loops.
For Each number As Integer In numbers and For Each letter As String In letters
   MsgBox(number.ToString & letter & " ")
Next

```

What do I need to do to get output that looks like this? :

> 
> 1a  
> 
>  4b  
> 
>  7c
> 
> 
>
