You can also use looping constructs, such as foreach, for, and while loops, to refer to the elements in an array. For example, to use a foreach loop to display the elements in the $a array, type:PowerShell Copy $a = 0..9 foreach ($element in $a) { $element } ...
The problem comes with the values I have in my array that is in the$dvariable. In Windows PowerShell, if I add 5 to my$dvariable, I end up actually adding the value as another element in the array. This is shown here: PS C:\> $d + 5 ...
If there are no matches in the collection, comparison operators return an empty array. For example: PowerShell Copy $a = (1, 2) -eq 3 $a.GetType().Name $a.Count Output Copy Object[] 0 There are a few exceptions: The containment and type operators always return a Boolean ...
