An array has a special property called "Length", which holds the length of the array or the number of members in the array.

The "Length" property can help you to loop through all members using a simple "For {...}" loop as shown below:

$w = @("Sun","Mon","Tue","Wed","Thu","Fri","Sat")
"There are "+$w.Length+" days in a week:"
For ($i=0; $i -lt $w.Length; $i++) {
   "   "+$w[$i]

You can also the "Foreach (...) {...}" loop to loop through each member in array as show in the following example:

$w = @("Sun","Mon","Tue","Wed","Thu","Fri","Sat")
"Week days:"
Foreach ($d in $w) {
   "   "+$d
