You want to create a list of squares of numbers from 1 to 5 using ForEach-Object. Which command achieves this and outputs the results?

A1..5 | ForEach-Object { $_ * $_ }

B1..5 | ForEach-Object { $square = $_ * $_ }

C1..5 | ForEach-Object { Write-Output $_ * $_ }

D1..5 | ForEach-Object { exit $_ * $_ }

Step-by-Step Solution

Solution:

Step 1: Understand output behavior
Expressions inside the script block output their result automatically.
Step 2: Evaluate each option
1..5 | ForEach-Object { $_ * $_ }: 1..5 | ForEach-Object { $_ * $_ } outputs squares directly. 1..5 | ForEach-Object { $square = $_ * $_ } only assigns without output. 1..5 | ForEach-Object { Write-Output $_ * $_ } has syntax error due to missing parentheses around $_ * $_. 1..5 | ForEach-Object { exit $_ * $_ } uses exit which terminates PowerShell after first item.
Final Answer:
1..5 | ForEach-Object { $_ * $_ } -> Option A
Quick Check:
Direct expression outputs results in ForEach-Object [OK]

Quick Trick: Use direct expressions inside ForEach-Object to output results [OK]
