SharePoint PowerShell Help

I’m looking to create a quick PowerShell script that will ask for the managed accounts to create in SharePoint and then just loops through until the user is no longer wanted to create anymore accounts.  This is what I have so far and I’m looking for any feedback.  Thanks

#Create Managed Accounts for SharePoint
Write-Host “This script must be run as administrator!”
$create = Read-Host “Do you want to create a managed account(y/n)?”

Do
{
If($create -match “y”)
{$cred = Get-Credential
New-SPManagedAccount -Credential $cred}
$create = Read-Host “Do you want to create a managed account(y/n)?”
}
While($create -match “y”)

#Get a list of all managed accounts.
Get-SPManagedAccount
