💼 Career

Understanding type casting helps automate data processing and validation in scripts for IT and DevOps roles.

1

Create a string variable with a number

Create a string variable called numberText and set it to the text "123".

PowerShell

# Create a string variable called numberText and set it to "123"
# Your code here

Need a hint?

Use double quotes to create a string in PowerShell.

2

Create a variable for the integer

Create a variable called numberInt to hold the integer value after conversion.

PowerShell

$numberText = "123"
# Create a variable called numberInt to hold the integer
# Your code here

Need a hint?

Initialize the variable with 0 before casting.

3

Use type casting to convert the string to an integer

Use type casting to convert numberText to an integer and store it in numberInt. Use [int] before the variable to cast.

PowerShell

$numberText = "123"
$numberInt = 0
# Cast numberText to int and assign to numberInt
# Your code here

Need a hint?

Use [int]$numberText to convert the string to an integer.

4

Print the integer value

Print the value of numberInt using Write-Output.

PowerShell

$numberText = "123"
$numberInt = [int]$numberText
# Print the integer value
# Your code here

Need a hint?

Use Write-Output $numberInt to print the number.
