Challenge - 5 Problems

💻 Command Output

What is the output of this PowerShell here-string?

Consider the following PowerShell script using a here-string. What will be the exact output when this script runs?

PowerShell

$text = @"
Hello,
This is a multiline
string.
"@
Write-Output $text

A

Hello,
This is a multiline
string.

B Hello, This is a multiline string.

C "Hello,\nThis is a multiline\nstring."

D Hello,This is a multilinestring.

💡 Hint

Remember that here-strings preserve line breaks exactly as typed.

PowerShell here-strings preserve all line breaks and spaces exactly. The output will include the new lines as in the string.

📝 Syntax

Which option correctly defines a here-string in PowerShell?

Select the option that correctly creates a multiline string using a here-string in PowerShell.

A

$str = @"
Line 1
Line 2
'

B

$str = @"
Line 1
Line 2
"@

C

$str = @'
Line 1
Line 2
"@

D

$str = '@
Line 1
Line 2
@'

💡 Hint

Here-strings start with @" and end with "@ or start with @' and end with '@ but must match.

Option B correctly uses @" and "@ to define a double-quoted here-string. Option B uses single quotes but the closing is incorrect. Options C and D have syntax errors.

Why does this here-string cause an error?

This PowerShell code throws an error. What is the cause?

PowerShell

$text = @"
This is a test
  "@
Write-Output $text

A The closing delimiter "@" must be alone on its line with no spaces.

B Here-strings cannot contain the word 'test'.

C The opening delimiter @" is missing a closing quote.

D Write-Output cannot print here-strings.

💡 Hint

Check how the closing delimiter is placed in the code.

In PowerShell, the closing delimiter of a here-string must be alone on its line with no spaces or characters before or after it. Here, "@" is not alone, causing the error.

How to include variables inside a here-string?

Given $name = "Alice", which here-string will correctly include the variable's value in the output?

PowerShell

$name = "Alice"
$text = @?
Hello, $name!
Welcome.
?@
Write-Output $text

A

$text = @'
Hello, " + $name + "!
Welcome.
'@

B

$text = @'
Hello, $name!
Welcome.
'@

C

$text = @"
Hello, '$name'!
Welcome.
"@

D

$text = @"
Hello, $name!
Welcome.
"@

💡 Hint

Double-quoted here-strings allow variable expansion, single-quoted do not.

Double-quoted here-strings (@" "@) expand variables inside. Single-quoted (@' '@) treat variables as literal text.

What is the number of lines in the output of this here-string?

How many lines will the following PowerShell script output?

PowerShell

$text = @"
Line1

Line3
Line4
"@
Write-Output $text | Measure-Object -Line

A 4

B 3

C 5

D 6

💡 Hint

Count all lines including empty ones preserved by the here-string.

The here-string includes 5 lines: Line1, empty line, Line3, Line4, and the final newline creates a fifth line.
