I am taking a beginners class in programming and I am very lost. I need
to design a program that models the worm's behavior in the following
scenario: A worm is moving toward an apple. Each time it moves the worm
cuts the distance between itself and the apple by its own body length
until the worm is close enough to enter the apple. The worm can enter
the apple when it is within a body length of the apple. I now I need to
use an iteration control structure but have no idea where to start or
what to do in this one. Can some one help?
