For loop in PowerShell - Mini Project: Build & Apply

Using a For Loop in PowerShell

📖 Scenario: You are organizing a small event and have a list of guests. You want to greet each guest with a personalized message.

🎯 Goal: Build a PowerShell script that uses a for loop to print a greeting message for each guest in the list.

📋 What You'll Learn

Create an array of guest names

Create a variable to hold the number of guests

Use a for loop to iterate over the guest names

Print a greeting message for each guest

💡 Why This Matters

🌍 Real World

Automating repetitive tasks like sending personalized messages to a list of contacts.

💼 Career

Understanding loops is essential for scripting tasks in system administration, automation, and DevOps roles.

1

Create the guest list array

Create an array called guests with these exact names: "Alice", "Bob", "Charlie", "Diana".

PowerShell

# Create an array called guests with the names "Alice", "Bob", "Charlie", "Diana"
# Your code here

Need a hint?

Use @() to create an array in PowerShell.

2

Create a variable for the number of guests

Create a variable called count that stores the number of guests in the guests array using the .Count property.

PowerShell

$guests = @("Alice", "Bob", "Charlie", "Diana")
# Create a variable called count that stores the number of guests
# Your code here

Need a hint?

Use $guests.Count to get the number of items in the array.

3

Write the for loop to greet each guest

Write a for loop that uses a variable i starting at 0 and runs while i is less than count. Inside the loop, access each guest by $guests[i].

PowerShell

$guests = @("Alice", "Bob", "Charlie", "Diana")
$count = $guests.Count
# Write a for loop with variable i from 0 to count - 1
# Your code here

Need a hint?

Use for ($i = 0; $i -lt $count; $i++) to loop through the array indexes.

4

Print greeting messages inside the loop

Inside the for loop, add a Write-Host statement to print: "Hello, $guest! Welcome to the event.".

PowerShell

$guests = @("Alice", "Bob", "Charlie", "Diana")
$count = $guests.Count
for ($i = 0; $i -lt $count; $i++) {
    $guest = $guests[$i]
    # Print greeting message for each guest
    # Your code here
}
