• Week 2 Class 2 Tue Jan 20 Posted: Jan 20

  After Class

  • Exercise 5: Rainfall I

    • I posted a feedback report, Report1.md, in your repository under the branch feedback. I strongly suggest looking at it on GitHub:

    • I posted the scores and any additional comments in Brightspace

    Points were taken off for:

    • Differences between your code for a commit and my code in the example
    • Not following the exact format of the header comment
    • Typos in words
    • Less or more than 3 commits
    • Wrong form of the action in the commit message. It is "Add", not "Added", "Adding", or "add".

    Also, do not use term "assignment" or "exercise" in your code. We simulate working on real code.

    If you have spacing or wording to fix, you can fix them. However, these commits must start with the word "Fix". Not "Fixing", "Fixed", or "fix", but "Fix".

  Agenda

  • Guide: GitHub Authentication
  • Setup for Exercise 6: Rainfall I

  • Exercise 5: Statement Design Quiz

    • Completed during class
    • All solutions in a question produce the same result
    • Must choose the "best" choice, and state why it is better
    • If you complete the Design Quiz, you will get full credit for this exercise
  • Notes: Rainfall Coding Practices

  • Exercise 6: Rainfall I

    You can follow along and see the commits that I make in class:

    OOPS26-Rainfall-020

    If you have any questions or issues, make sure to contact me.

  • Notes: Software Design Characteristics

  Unless otherwise noted, exercises are due by 3:30 pm on Wed Jan 21

• Exercise 6: Rainfall I Posted: Jan 20

  Take the starting rainfall.cpp code and make the changes that I make in class. This means the exact same code changes and exact commit message.

  Your code is in a repository from GitHub Classroom:

  1. Log in to your GitHub account.
  2. Click on the invitation link (GitHub Classroom Rainfall) on the main course page in Brightspace.
  3. Follow the directions to link your GitHub account to your UA ID.

  Environment

  1. Local

     This would be on your own machine with local files.

     First, you need to authenticate your local environment with GitHub: Guide: GitHub Authentication. This only has to be done once per environment, e.g. WSL on Windows.

     Then you clone the repository. Cloning creates a local repository that is a copy of your repository at GitHub.

     You can get the repo link from the button <> Code on GitHub, then under Local and HTTPS.

     Cloning a repository creates a directory with the name of your repository, e.g., _rainfall-_. To work on the files, you need to move into that directory:

  2. GitHub Codespaces

     GitHub Codespaces provides a development environment in the browser. When you create one from your GitHub Repository, you are already authenticated with GitHub and have a cloned repository, so you can start working right away.

     You can start a Codespace from the <> Code button on GitHub, then under Codespaces.

  Build Setup

  Git Workflow on Rainfall

  1. Edit files locally, e.g., add a header comment to the file rainfall.cpp
  2. Build, run, and check your work
  3. View your changes
  4. Commit current changes to the local repository:
  5. Push your local commits to the GitHub repository:
  6. View and verify your changes at GitHub in your browser Do not skip this verification
  7. View your commits locally

  Note Your code must build and compile. If you have a build warning or error, fix these before making any more changes to the code.

  Note You must commit each change that I make separately and use the exact commit message that I use in class

• Snow Day Posted: Jan 15

  After Class

  Class on Thursday, Jan 20 will be online in Teams.

  You should see a meeting in your Teams Calendar. The name of our Team is _CPSC 421-020 OOP _.

  I will also post a direct link in Brightspace.

  Agenda

  Campus is closed today, so no class.

  I am not holding office hours, but am available for questions via email.

  In in place of a class meeting, complete the following:

  • Read the rest of Notes: Software Design. We covered up to slide 30 . If you type g on the slide page a Jump to slide appears so you can go directly to that slide.
  • Exercise 4: Software Design Crossword Due 3:30 pm on Friday, Jan 16
  • Exercise 3: Development Environment Survey Due 3:30 pm on Friday, Jan 16. I am giving you extra time to fix any issues with the CMake and Ubuntu upgrades.

  • CMake & Ubuntu Versions

    As stated in the Development Environment: Tools the cmake version must be 4.2.1 or higher. Some of you have less recent versions, even though the instructions stated you need to be at 4.2.1 for cmake. Follow the instructions to install the APT repository from Kitware (CMake people).

    For Linux, upgrade your Ubuntu using:

    You should also be on Ubuntu 24.04, not an older version. To convert, first upgrade as above, then enter the command:

    Use the Development Environment: Tools to check your versions.

    If you make any of these changes, then edit or fill out a new survey.

  Announcements

  • Syllabus
  • Office Hours

  • GitHub We use GitHub and GitHub Classroom in the class to manage source code for projects, exercises, and examples. You are required to have a GitHub account.

    Optionally, you can apply for the Student Github Developer Pack and get a free GitHub Pro account. To apply, your account email can be a school account, or a personal account if you upload documents to prove your current enrollment status.

  • GitHub Codespaces All exercises and projects include GitHub Codespaces as an option. It runs in and browser and offers a development environment with Visual Studio Code, along with a shell to enter commands for building (compiling and linking) and running your program. It automatically clones your GitHub repository. However, it does not automatically save your code changes back to GitHub; you must use git commands to do so.
  • Development Environment: Tools While GitHub Codespaces is great for short-term exercises, you'll want to work on long-term projects directly on your computer. Follow the instructions in the guide to set up your development environment. Department servers have older versions of g++ and cmake, so avoid relying on them.

  • O'Reilly Online Learning The course textbook is available in O'Reilly Online Learning.

    You do not have to be on the campus network (e.g., via VPN) to access O'Reilly Online Learning.

    To access content, click the "Institution not listed?" link below the dropdown and enter your UA email. You will then create an account and use that account from now on.

    For more information: Library LibGuide

  Agenda

  • Exercise 1: OOP Survey

  • Exercise 2: Syllabus Crossword

    1. Fill out the crossword in your browser. Do not print and fill out on paper.
    2. Print to a PDF using the Print Button or the Print feature in your browser. Try to include the headers and footers in the PDF.
    3. Upload the PDF of the completed crossword to Brightspace in Assessments/Assignments.

  • Exercise 3: Development Environment Survey

    The survey is available from the link of this exercise. There is nothing to upload to Brightspace.

    This exercise is due by 1 pm on Thu, Jan 15.

  • Notes: Software Design

  Unless otherwise noted, exercises are due by 3:30 pm on Wed Jan 14

• Welcome Posted: Jan 06

  Greetings and welcome to CPSC 421 Object-Oriented Programming for Spring 2026.

  • Syllabus The syllabus for the course is on the main course page. It is a draft that I will finalize before our first class meeting.
  • Survey The first exercise is to fill out the class survey. The survey is due after our first class meeting, but you can complete it before.
  • Development Environment Development Environment: Tools is a guide for setting up your programming development environment for the class. It is a good idea to start now as you will need this early in the course.

  • GitHub In the class, we use GitHub and GitHub Classroom to manage source code for projects, exercises, and examples. You are required to have a GitHub account.

    Optionally, you can apply for the Student Github Developer Pack and get a free GitHub Pro account. To apply, your account email can be a school account or a personal account if you upload documents to prove your current enrollment status.

  See you on Tuesday, Jan 13 at  3:30 - 4:45 pm in Arts & Sciences (CAS) room 136
