💡 Hint

Common Mistakes

Using [string] instead of [int] will keep the value as text.

Using [bool] will convert to true or false, not a number.

In PowerShell, [int] casts a value to an integer type.

💡 Hint

Common Mistakes

Casting to [int] does not change the value.

Casting to [string] converts the number to text.

Casting 0 to [bool] results in False, as 0 is considered false in boolean context.

💡 Hint

Common Mistakes

Using [int] causes an error because 'True' is not a number.

Using [string] keeps the value as text.

Casting the string 'True' to [bool] converts it to the boolean value True.

4fill in blank

hard

Fill both blanks to cast the string '3.14' to a double and then to an integer.

$piInt = [[2]]$piDouble

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Casting directly from string to int loses the decimal part or causes errors.

Casting to [bool] is not appropriate here.

First cast the string to [double] to get the decimal number, then cast to [int] to get the integer part.

5fill in blank

hard

Fill all three blanks to create a hashtable with keys as uppercase strings and values as integers greater than 3.

PowerShell

$words = @('one', 'two', 'three', 'four')
$result = @{ [1] = [2] for $w in $words if [3] }

Drag options to blanks, or click blank then click option'

A$w.ToUpper()

B$w.Length

C$w.Length -gt 3

D$w

💡 Hint

Common Mistakes

Using $w as key keeps keys lowercase.

Filtering with incorrect condition includes unwanted words.

The keys are uppercase words, values are their lengths, filtered to lengths greater than 3.
