CPSC 421-010 Object-Oriented Programming Spring 2026

Week 14 Class 23 Thu Apr 16 Posted: Apr 16

After Class

• Project 4 I added back the manual instructions to change from template to handler. You can do that as an alternative to the pull request. If you did pull the request handler before you were done with template, then let me know and I can manually fix it.

  If you have any issues or questions on converting from template to handler for the file setup, let me know.

• Guide: Contiguous Container Allocation I renamed this to clarify that reallocation is for contiguous containers. I also added links to the code where the new size is calculated.

Announcements

• Project 4
• Project 3 I posted the feedback on the diagrams. I also posted scores for all the separate parts: v3a 40%, v3xmlstats 25%, v3identity 25%, Class Diagram 10%, and Sequence Diagram 10%. I took your total points of these out of 100.

• Exercise 81: Software Development Habits Survey This is an optional exercise that involves taking an outside survey. The survey involves making changes to code in a browser-based editor. See the Brightspace anouncement for more information, and how to get a screenshot to prove your survey completion.

  Upload the screenshot to Brightspace. Due by Noon on Fri, Apr 17.

• Exercise 82: Encoder Reminder that both parts, the changes in the commits and the asciinema session, were required.
• Exercise 85: Design Pattern Factory Method Quiz Scores are posted and correct answers released.

Agenda
