Content:

This lecture is devoted to the notion of Encapsulation and basic Object Oriented Design relationships.
  1. The Syllabus describes topics to be covered, reading material for you to digest before coming to class, and due dates for the assigned projects.

  2. Readings for Lecture #3

    Text: skim chapters 2-6, read chapter 7
    Project #1
    C++ Classes, Templates

  3. Glossary of Terms

    • Encapsulation:
      Restricting all access to a class's state to member functions of the class.
      This ensures that the class state is always valid, since only the class's methods initialize and change it.

  4. Project #1

    Project #1 statement, Project1HelpS2019
    Dissecting the Project #1 statement - What is hard? What is easy? Suggestions. Project code - Goals, Tasks, Structure, design trade-offs, C++ specific details. Recommended strategy:
    Define packages for at least the following:
    • Executive - manages demonstration of your work on Project #1
    • Converter
    • Display
    You will probably want to add packages for helper code from Project1HelpS2019, e.g.:
    • DirectoryExplorer
    • Process (to help show you meet requirements)
    Note: you are required to demonstrate explicitly and conclusively that you meet all the requirements your code implements. The biggest part of that is to show each of the files converted from the specified path. You will find the Process project will provide a lot of help for that.
    Resources for Project #1:

    Visual Studio Help Slides, Project Properties, doc
    Project Submissions, Compile.bat and Run.bat

  5. Encapsulation:

    Encapsulation Presentation, pptx

  6. Class Relationships:

    Class Relationships, Object Layout Diagram Compound Objects Code Snap
    Read this code and understand thoroughly - visit Stroustrup (class text) as needed class relationships - more details, class layout
  7. Equivalent Syntaxes
  8. first look at STL notes, pptx
    The Standard Template Library (STL) provides a set of useful containers, iterators, and algorithms. You can use the containers without knowing too much about how templates work. We will get to that soon.
  9. Software Design
  10. Value Types Presentation, pptx
