Question

Using Powershell:

[Show proper command to define variables as string and integer and for the following arithmetic operations.]
$lin = ""20"" and $ux = 21.
Define lin as string and ux as interger. What will be the output of:
1. $lin + $ ux
2. $ux + $lin

Answer 1

In PowerShell, $lin as a string "20" and $ux as an integer 21 will lead to their concatenation when using the + operator, resulting in "2021" for $lin + $ux and "2120" for $ux + $lin.

Step-by-step explanation:

To define variables as a string and an integer in PowerShell, you would typically use the following syntax:

• $lin = "20" # This is a string because it's enclosed in quotes
• $ux = 21 # This is an integer because there are no quotes

Knowing this, let's explore what would happen with the two arithmetic operations:

1. $lin + $ux - This operation will treat both operands as strings and concatenate them, resulting in "2021".
2. $ux + $lin - Similar to the first operation, PowerShell will convert the integer to a string and concatenate both, resulting in "2120".

In PowerShell, when you mix strings and integers in an operation, it tries to convert the integer into a string and then perform the operation.
