loops are Fun (You Can say that again)
We’ve used loops since our very first program to
draw repeating shapes. Now it’s time to learn how to
build our own loops from scratch. Whenever we need
to do something over and over again in a program,
loops allow us to repeat those steps without having to
type each one separately. Figure 4-1 shows a visual
example—a rosette made up of four circles.
