I am new to PowerShell and I wanna try out a "Hello, (name)." program. Problem is I can't find an input function nor an output one.

Is there a PowerShell function I can use to get input like input in Python and output like cout in C++?

    have you read the Tour page for this site? [grin] you are in violation of the rules by not posting code that "doesn't work as expected". Commented Sep 18, 2020 at 9:35

    as for output ... anything not assigned to something will be sent to the success/output stream. there is no dedicated output method. however, there are several Write-* cmdlets. i recommend you read the Get-Help info on them. Commented Sep 18, 2020 at 9:37

    input also lacks a dedicated method. there are, however, the Read-* cmdlets ... [grin] Commented Sep 18, 2020 at 9:38

    @Lee_Dailey First, I did read the tour page. Secondly, I don't know how PowerShell works yet and I can't find a way to get the input and output, but I guess cmdlets will help. Third and lastly, I actually did the same thing as this question: Getting input from the user in Lua which I think that I probably didn't violate the rules. Commented Sep 19, 2020 at 12:45

    [1] reading all the way thru the tour page normally gives you 100 reputation points. you only show 5 ... so something went wrong. [grin] ///// [2] i showed you a clear hint about Read-*. i recommend you ReadTheFriendlyManual ... Get-Command *read* and Get-Help Read-Host. ///// [3] i also pointed out how to get the equivalent of print via the various Write-* cmdlets. again, take a look at the help system for more info.

Try:

$User = Read-Host -Prompt "Name"
echo "Hello $User"

Powershell support many languages.

There is another way, Write-Host.
