Question about drawing the hollow rectangle and diamond

How to Draw a hollow rectangle, triangle and diamond using the C + + using Four rings or something like that

One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them...

So tell me, mortal man doomed to die, what idea do you have, what algorithm have you come up with, to draw a hollow rectangle? What examples of this hollow rectangle do you have, anyway?
