Summary: Learn how to use Windows PowerShell to change the value of an element in an array.

 How can I use Windows PowerShell to update one of the values in one of the elements of an array?

 Use the Item method to retrieve the element and assign a new value. Here is an example of
           updating the value of the first element in an array:

$a = 1,2,3,4,5

$a.Item(0) = 12

$a

Note  Remember that in Windows PowerShell, all arrays are zero-based. This means that the first
element is actually element 0.
