In PowerShell, an if statement allows you to execute a block of code based on the evaluation of a conditional expression. An elseif clause allows you to specify additional conditions that are checked only if the previous if or elseif condition was false. An else clause specifies a block of code that is executed if all the previous conditions were false.
$x = 10
if ($x -gt 15) {
# This block of code is executed if $x is greater than 15
Write-Host "x is greater than 15"
} elseif ($x -lt 5) {
# This block of code is executed if $x is less than 5
Write-Host "x is less than 5"
} else {
# This block of code is executed if none of the previous conditions are true
Write-Host "x is between 5 and 15"
}
