💼 Career

Knowing switch statements is useful for scripting tasks in IT, system administration, and automation roles.

1

Create fruit color and fruit name variables

Create a variable called $fruitColor and set it to "red". Create another variable called $fruitName and set it to "Apple".

PowerShell

# Create variables $fruitColor and $fruitName
# Your code here

Need a hint?

Use = to assign values to variables. Strings must be in double quotes.

2

Add a switch statement for fruit color

Add a switch statement that checks the value of $fruitColor. Prepare cases for "red", "yellow", and "green". For now, just add the switch block without any actions inside.

PowerShell

$fruitColor = "red"
$fruitName = "Apple"

switch ($fruitColor) {
    # Your code here
}

Need a hint?

Use switch ($fruitColor) { "red" { } "yellow" { } "green" { } } structure.

3

Add actions inside switch cases

Inside the switch statement, add Write-Output commands for each color case. For "red", print "$fruitName is a red fruit". For "yellow", print "$fruitName is a yellow fruit". For "green", print "$fruitName is a green fruit".

PowerShell

$fruitColor = "red"
$fruitName = "Apple"

switch ($fruitColor) {
    "red" { # Your code here }
    "yellow" { # Your code here }
    "green" { # Your code here }
}

Need a hint?

Use Write-Output with double quotes and $fruitName inside the string.

4

Print the fruit category

Run the script to print the fruit category based on the $fruitColor. Use Write-Output inside the switch statement as implemented. The output should be exactly: Apple is a red fruit.

PowerShell

$fruitColor = "red"
$fruitName = "Apple"

switch ($fruitColor) {
    "red" { Write-Output "$fruitName is a red fruit" }
    "yellow" { Write-Output "$fruitName is a yellow fruit" }
    "green" { Write-Output "$fruitName is a green fruit" }
}

# Run the script to see the output

Run the script and check the output matches exactly.
