Practice - 5 Tasks

1fill in blank

easy

Complete the code to check if both conditions are true using the correct logical operator.

PowerShell

if ($a -gt 5 [1] $b -lt 10) { Write-Output "Both true" }

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

💡 Hint

Common Mistakes

Using -or instead of -and causes the condition to be true if either is true.

Using -not negates a single condition, not both.

The -and operator checks if both conditions are true.

medium

Complete the code to check if either condition is true using the correct logical operator.

PowerShell

if ($x -eq 0 [1] $y -eq 1) { Write-Output "At least one is true" }

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

💡 Hint

Common Mistakes

Using -and requires both conditions to be true, which is not what we want here.

Using -not negates a condition, not combines two.

The -or operator returns true if at least one condition is true.

3fill in blank

hard

Fix the error in the code by choosing the correct logical operator to negate the condition.

PowerShell

if ([1] ($status -eq 'Success')) { Write-Output "Not successful" }

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

A-or

B-not

C-and

D-xor

💡 Hint

Common Mistakes

Using -and or -or here causes syntax errors or wrong logic.

For negation, only -not works correctly.

The -not operator negates the condition, so it is true when the status is not 'Success'.

4fill in blank

hard

Fill both blanks to create a condition that is true when $a is greater than 10 and $b is not equal to 5.

PowerShell

if ($a [1] 10 [2] $b -ne 5) { Write-Output "Condition met" }

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

B-lt

C-and

💡 Hint

Common Mistakes

Using -lt instead of -gt reverses the comparison.

Using -or allows the condition to be true if only one side is true.

-gt means greater than, and -and combines both conditions to be true.

5fill in blank

hard

Fill all three blanks to create a condition that is true when $x is less than 5 or $y is not equal to 10, but not when $z is true.

PowerShell

if (($x [1] 5 [2] $y -ne 10) -and [3] $z) { Write-Output "Complex condition met" }

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

A-lt

B-or

C-and

D-not

💡 Hint

Common Mistakes

Using -and instead of -or changes the logic.

Not negating $z causes the condition to behave incorrectly.

-lt means less than, -or combines the first two conditions, and -not negates the last condition.
