C ++ PlusData Structures Third Edition Nell Dale JONES AND BARTLETT COMPUTER SCIENCE Software Engineering Principles After studying this chapter, you should be able to Describe the general activities in the software life cycle Describe the goals for “quality” software Explain the following terms: software requirements, software specifications, algorithm, information hiding, abstraction, stepwise refinement Explain and apply the fundamental ideas of top-down design Explain and apply the fundamental ideas of object-oriented design Identify several sources of program errors Describe strategies to avoid software errors Specify the preconditions and postconditions of a program segment or function Show how deskchecking, code walk-throughs, and design and code inspections can improve software quality and reduce the software development effort Explain the following terms: acceptance tests, regression testing, verification, validation, functional domain, black-box testing, white-box testing State several testing goals and indicate when each would be appropriate Describe several integration-testing strategies and indicate when each would be appropriate Explain how program verification techniques can be applied throughout the software development process Create a C++ test driver program to test a simple class Goals 10 | : Software Engineering Principles f=ma Figure 1.1 An abstraction includes the essential details relative to the perspective of the viewer. Thus, while we may see a car as a means to transport us and our friends, the automotive brake engineer may see it as a large mass with a small contact area between it and the road (Figure 1.1). What does abstraction have to do with software development? One of our major goals is to convince you to use abstractions to manage the complexity of developing software. Decomposing a system into modules helps us manage complexity.
