  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".

  • 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
