Sir is it correct way iam getting missing statement block in switch statement clause

Answer 1

Ok, I would change the script to do this:
# Step 1) install Chocolatey when needed
if (-not (Test-Path -Path "$env:ProgramData\Chocolatey\choco.exe" -PathType Leaf)) {
# from https://chocolatey.org/install
Set-ExecutionPolicy Bypass -Scope Process -Force
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072
Invoke-Expression ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))
}
# Step 2) define the array of packages you are offering
$Packages = 'googlechrome','firefox','codeblocks','windbg','nasm',
'explorersuite','pestudio','vscode','sysinternals','python'
# Step 3) define the Show-Menu function
function Show-Menu {
Clear-Host
Write-Host "**********************************************"
Write-Host "LIST OF SOFTWARES"
# write the options using the array of packages
for ($i = 0; $i -lt $Packages.Count; $i++) {
# {0,2} means right align with spaces to max 2 characters
Write-Host ('{0,2}. {1}' -f ($i + 1), $Packages[$i])
}
Write-Host " q. Exit the script"
Write-Host "*************************************************"
Write-Host
}
# Step 4) enter an endless loop you only exit if the user enters 'q'
while ($true) {
Show-Menu
$UserInput = Read-Host "Enter the software number to be installed"
# test if the user wants to quit and if so, break the loop
if ($UserInput -eq 'q') { break }
# test if the user entered a number between 1 and the total number of packages (inclusive)
if ([int]::TryParse($UserInput,[ref]$null) -and 1..$Packages.Count -contains [int]$UserInput) {
# here you install the chosen package using the array index number (= user input number minus 1)
$packageIndex = [int]$UserInput - 1
Write-Host "Installing $($Packages[$packageIndex])"
choco install $Packages[$packageIndex] -y
}
else {
$availableOptions = 1..$Packages.Count -join ','
Write-Host "Error in selection, choose $availableOptions or q" -ForegroundColor Red
}
$null = Read-Host "Press Enter to continue"
}
