Using PowerShell to solve three-way test development pen Questions

On the Internet saw three test development of the pen questions, the answer is in Python solution. This is the time to learn about PowerShell, practice:)

1. Verify the mailbox format

2. Get the suffix name of the URL

3. Get the time of the previous day or the previous second

My solution is:

1 #Check Email Format2Write-host"Please input your email address"3 $email=read-Host4 $regular="[A-za-z0-9]\@[a-za-z0-9]\. [A-za-z0-9]"5 if($email -match $regular)6{Write-host"Email is correct, pass!"-Foregroundcolor Green7}Else{8Write-host"Email is wrong, waring!"-Foregroundcolor Red9 }Ten  One #------------------------------------------------------------- A  - #Get the URL name extensions -Write-host"Please input one URL" the $url=read-Host - $extension=($url. Substring ($url. LastIndexOf (".") +1)) -Write-host"The URL extension is:" $extension-Foregroundcolor Green -  + #------------------------------------------------------------ -  + #Get the previous time A $Now=get-Date at $Now. AddDays (-1)#Yesterday - $Now. AddSeconds (-1)#previous Second

Come on! 2017!
