If statements

$temp = 60

if ($temp -lt 50){ Write-Host "It is cold" } elseif ($temp -ge 50){ Write-Host "It is hot" } else { Write-Host "Nah" }

Switch statements

$day = "Tuesday"

switch ($day) { "Monday" { Write-Host "Today is Monday"} "Tuesday" { Write-Host "Today is Tuesday"} }

Comparisons

$a = 10 $b = 20

if ($a -eq $b) { Write-Host "a is euqal to b" } elseif ($a -ne $b){ Write-Host "a is not equal to b" }

if ($a -gt $b){ Write-Host "a is greater than b" } elseif ($a -lt $b) { Write-Host "a is less than b" }

if ($a -ge $b){ Write-Host "a is greater than or euqal to b" } elseif ($a -le $b){ Write-Host "a is less than or equal to b" }

For Loop

for ($i = 1; $i -le 10; $i++) { Write-Host $i }

ForEach Loop

$fruits = @("apple", "banana", "grape")

foreach ($fruit in $fruits) { Write-Host $fruit }

Creating a Hash Table

$ages = @{ "John" = 30 "Sarah" = 25 "Mike" = 40 }

Accessing Hash Table Objects

$ages = @{ "John" = 30 "Sarah" = 25 "Mike" = 40 } $johnAge = $ages["John"] Write-Host "John's age is $johnAge"
