Powershell For loops

For loops have three parts:

For ($1; $2; $3){

}

$1 is the initial value
$2 is the condition
$3 is what to loop

first, $1 is checked against the condition ($2) then, $3 is run and checked against the condition, if it still matches the condition, the loop continues.
if it no longer matches the condition, the loop exits.

Broken Example Code:

#I couldnt figure out the factorials and it kept getting me confused and stuck so ill use addition instead. >dealwithit.gif

clear-host
$nums =@()
$array =@()

[int]$times = read-host “how many sums will you do”

For ($i=0; $i -lt $times; $i++)
{

$num1 = read-host “enter a number”
$num2 = read-host “enter a second number”

$num3 = [int]$num1 + [int]$num2

$array = @($num1,$num2,$num3)
write-host $num1″+”$num2″=”$num3
}
For ($i=0; $i -lt $times; $i++){
write-host “Nums”`t”Sum”
write-host $array[-$array.count]$array[-2] `t $array[-1]
write-host $array[$i]`t$
}
