What is the output of this PowerShell code?

Consider the following PowerShell script:

$a = $true
$b = $false
$result = $a -and $b
Write-Output $result

What will be printed?

PowerShell

$a = $true
$b = $false
$result = $a -and $b
Write-Output $result

A False

B True

C 1

D 0

💡 Hint

Remember that -and returns True only if both sides are True.

The -and operator returns True only if both operands are True. Here, $a is True but $b is False, so the result is False.

💻 Command Output

What does this PowerShell expression output?

What is the output of this code?

Write-Output ($false -or $true)

PowerShell

Write-Output ($false -or $true)

A False

B True

C 0

D 1

💡 Hint

The -or operator returns True if at least one operand is True.

Since one operand is True, the -or operator returns True.

Which option correctly assigns a Boolean value in PowerShell?

Which of the following lines correctly assigns a Boolean True value to the variable $flag?

A $flag = True

B $flag = TRUE

C $flag = $True

D $flag = true

💡 Hint

PowerShell Boolean constants start with a dollar sign and capital T.

In PowerShell, Boolean constants are case-insensitive but must be prefixed with a dollar sign, like $True or $False. 'True' without $ is treated as a string or variable name.

🚀 Application

What is the output of this conditional check?

Given this script:

$value = 0
if ($value) { Write-Output 'Yes' } else { Write-Output 'No' }

What will it print?

PowerShell

$value = 0
if ($value) { Write-Output 'Yes' } else { Write-Output 'No' }

A Yes

B True

C 0

D No

💡 Hint

In PowerShell, non-null values are treated as True in conditionals.

In PowerShell, the integer 0 is treated as False in conditionals, so the else block runs and prints 'No'.

What error does this PowerShell script raise?

What error will this script produce?

$x = 'True'
if ($x -eq $True) { Write-Output 'Match' } else { Write-Output 'No Match' }

PowerShell

$x = 'True'
if ($x -eq $True) { Write-Output 'Match' } else { Write-Output 'No Match' }

A No error, outputs 'No Match'

B No error, outputs 'Match'

C TypeMismatchException

D Runtime error: Invalid comparison

💡 Hint

Check how PowerShell compares strings and Booleans.

PowerShell compares string 'True' to Boolean $True as not equal, so it outputs 'No Match' without error.
