PowerShell - Operators

Which of these is a valid use of the ternary operator in PowerShell 7+?

A$x = 5; if ($x -gt 3) { 'Yes' } else { 'No' }

B$x = 5; $result = $x -gt 3 ? 'Yes' : 'No'

C$x = 5; $result = if $x -gt 3 then 'Yes' else 'No'

D$x = 5; $result = $x gt 3 ? 'Yes' : 'No'

Step-by-Step Solution

Solution:

Step 1: Check PowerShell ternary syntax
PowerShell uses the syntax: condition ? true-value : false-value. $x = 5; $result = $x -gt 3 ? 'Yes' : 'No' matches this exactly.
Step 2: Identify incorrect syntax in other options
$x = 5; if ($x -gt 3) { 'Yes' } else { 'No' } uses if-else block, not ternary. $x = 5; $result = if $x -gt 3 then 'Yes' else 'No' uses invalid keywords 'then' and 'else'. $x = 5; $result = $x gt 3 ? 'Yes' : 'No' uses 'gt' which is invalid in PowerShell (requires '-gt').
Final Answer:
$x = 5; $result = $x -gt 3 ? 'Yes' : 'No' -> Option B
Quick Check:
Valid ternary syntax = $x = 5; $result = $x -gt 3 ? 'Yes' : 'No' [OK]

Quick Trick: Use -gt, not >, with ternary in PowerShell [OK]
