14. Simple Scripting Arguments not declared or typed Arguments not declared or typed function MyEcho { for ($i = 0; $i –lt $args.count; $i++) for ($i = 0; $i –lt $args.count; $i++) { “arg{0} = {1}” –f $i, $args[$i] “arg{0} = {1}” –f $i, $args[$i] }}

15. Advanced Scripting function Get-Total ( [String]$property = $(throw "Property Required"), [string]$formatString = "Total {1} = {0}" ) { Begin { $total = 0 { $total = 0 } Process Process { $total += $_.$property { $total += $_.$property } End End { $formatString -f $total,$property { $formatString -f $total,$property }} Arguments declared, typed, initialized
