Ada Plus Data Structures is the most up-to-date, student-friendly Ada text available. The text introduces and discusses such familiar topics as strings, sets, stacks, queues, lists, trees, graphs, and much more. The recurring theme throughout the text is modeling with levels of abstraction, presenting each class from three different perspectives their specification, their abstraction, and their implementation. Using this approach, the authors stress computer science theory and software engineering principles including information hiding, data encapsulation, data abstraction, stepwise refinement, and visual aids. With its Object-Oriented presentation, real-world applications, and traditional Dale Pedagogy, Ada Plus Data Structures is a pleasure to read and learn from. • New and key features Dale and McCormick provide an accessible introduction to object-oriented design methodologies, balanced with a clear presentation of traditional abstract data types, computer science theory, and software engineering practices • Unified Modeling Language ( UML) class diagrams and object-oriented approaches are used throughout the book • Expanded coverage of hashing • Reviews of principle Ada constructs are included within the text as a refresher for students • Includes the object.operation syntax as an alternative to the traditional package-operation syntax for invoking class operations • Introduces the Ada container class library • Many new chapter exercises and programming problems.
