Variable and Comparison Operators

Task 1

Assign a variable with each datatypes covered in the previous workshop The datatypes previous covered were “Boolean”, “String”, “Int”

• $BoolanVar = $True
• $StringVar = "This is a string"
• $IntVar = 42

---

Task 2

List all variables currently loaded in to memory. The noun within the cmdlet is “Variable”

• Get-Variable

• Get-Variable BoolanVar

• Get-Variable StringVar

• Get-Variable IntVar

---

Task 3

Multiple two Int variables together PowerShell can perform basic maths operators, such as “+”, “-“ and “*”

• $IntVar1 = 4
• $IntVar2 = 10
• $IntVar1 * $IntVar2

---

Task 4

First declare two Int variables. Then divided the first variable by the second and assign the result to a variable named $VariableResult The easiest way to do this is within the Integrated Scripting Environment (ISE) using multiple lines of code

• $IntVar3 = 10
• $IntVar4 = 2
• $VariableResult = $IntVar3 / $IntVar4

---

Task 5

Typecast a Variable as a “String” and assign it a value of 5 Remember to normal brackets [] rather than curly brackets {} when typecasting a variable

• [String]$TypecastVar = 5
