Determine the class average for the quiz
The top is, in effect, a complete representation of a program. Unfortunately, the top rarely conveys sufficient detail from which to write a Java program. So we now begin the refinement process. We divide the top into a series of smaller tasks and list these in the order in which they’ll be performed. This results in the following ...
