Content:

This lecture is devoted to hierarchical relationships in the C++ language, especially inheritance and composition.
  1. Syllabus
    Describes topics to be covered, reading material for you to digest before coming to class, and due dates for the assigned projects.
  2. new style casts demo, const pointers demo

  3. Readings for this Lecture:

    Class Text, CPPP:
    • review Chapter 7 - Classes
    • read carefully Chapter 15 - Object Oriented Programming

  4. Projects:

    Project #1, Project1HelpS17
    NoSql Database

    Policy for due date extensions - only for certified illness and work or interview trips out of town: one week extension, with proof. Only one extension per project.

  5. Class Hierarchy

    class relationships, doc
    class relationships - layout view, vsd
    ClassRelationships code folder
    Demonstrates code layout in memory.

    Compound Object creation
    You need to understand how constructor initialization is required to control the objects you create.

    Hierarchy Presentation
    Hierarchy is concerned with the relationships between classes - aggregation, composition, inheritance, and using.

    Three Tier Hierarchy - a common idiom

    Demonstrate Composition
    This project contains a number of demonstrations of basic composition relationships.

    Demonstrate Inheritance
    Contains demonstration of things to be careful with when using inheritance.

  6. Software Design Blog Entries:

    Software Design

    Object Oriented Design

    Parser - Object Oriented Design Example
  7. Software design presentations:

    • There is no receipe for good design - it's a creative process that usually strives to balance a number of competing factors.
    • Our goals are to build programs and software systems that are elegant and simple, make their intents clear, and make them fast and reliable.
    • The presentations below provide guidance to help move us toward those goals.

    Software Design Goals
    Design Goals and Attributes - used to measure designs.

    Design Strategies
    Discusses styles of design and binding.

    Design Guidelines
    Small principles and useful techniques

    Design Issues
    Practical issues and problems of design and implementation
