💡 Why This Matters

🌍 Real World

Scripts often need to create messages that change based on user data, like greeting users or showing status updates.

💼 Career

Understanding string interpolation helps automate reports, notifications, and user interactions in many IT and scripting jobs.

1

Create variables for name and age

Create a variable called $name and set it to the string "Alice". Create another variable called $age and set it to the number 30.

PowerShell

# Your code here

Need a hint?

Use = to assign values. Strings need double quotes.

2

Create a greeting message using string interpolation

Create a variable called $greeting and set it to a string that says Hello, my name is Alice and I am 30 years old. Use string interpolation with $name and $age inside double quotes.

PowerShell

$name = "Alice"
$age = 30
# Your code here

Need a hint?

Use double quotes and include variables directly inside the string.

3

Print the greeting message

Use the Write-Output command to print the variable $greeting.

PowerShell

$name = "Alice"
$age = 30
$greeting = "Hello, my name is $name and I am $age years old."
# Your code here

Need a hint?

Use Write-Output followed by the variable name to print.

4

Run the script and see the output

Run the script to display the greeting message exactly as: Hello, my name is Alice and I am 30 years old.

PowerShell

$name = "Alice"
$age = 30
$greeting = "Hello, my name is $name and I am $age years old."
Write-Output $greeting
# Run the script

Need a hint?

Make sure you run the script and check the output matches exactly.
