How to get the ith input argument?

I want to get the ith input argument such that:

./test.sh "what is" "where is" "how" "when"

Say if I want echo the value of the 2nd variable, it should print "where is"
If there is no blank in variable, using $@ $* can easily handle the problem, but I have no idea how to do this now..

..
Never mind, I figure it out..
just do command like

for arg
echo $arg....

Not smart...
