Problem 1
Explain the following: (a) The purpose of detailed design (list three benefits) (b) How it differs from software architecture (c) Why it is generally a questionable idea to go directly from architecture to implementation.
Problem 2
Your company produces software that controls a robot arm for manufacturing. Name four classes that would be appropriate members of your company's software framework. Explain your reasoning.
Problem 6
Describe in your own words the advantages of specifying preconditions, postconditions, and invariants. How, specifically, do they help to increase the quality of functions?
Problem 8
A classic Liskov substitution principle example consists of two classes, Square and Rectangle. Since a square is-a rectangle, the relationship between the two can be modeled using inheritance, with \(S q\) uare deriving from Rectangle. Suppose that Rectangle has methods to set/get the width, and set/get the length. Explain how this relationship between Square and Rectangle violates the Liskov substitution principle.
