Assign1: Getting Your C++ Legs

Due Tuesday, June 30 at 11:59 pm

• The assignment deadline is by the end of the day in Pacific Daylight Time. This means that you have until 11:59pm PDT on the day of the assignment deadline to submit the assignment.
• Submit by the end of the day Tuesday deadline for a small, “early-bird” bonus.
• All students have a pre-approved extension or "grace period" that extends until Wednesday end of the day PDT, with no penalty.
• The grace period expires at the end of the day Wednesday, after which we cannot accept further late submissions.
• Note that our Paperless submission system displays due dates and submission times in the PDT frame of reference.

Here it is – the first programming assignment of the quarter! This assignment is designed to get you up and running with the C++ language and the tools used in CS106B. The work involves a mix of coding, testing, and debugging tasks. By the end of this assignment, you'll have fully gotten your C++ legs under you! (our apologies for the bad pun…)

The code you will write involves expressions, control structures, functions, and string processing. You have prior experience with these concepts, but the tricky part is figuring how to map what you already know to the strange new world of C++. The transition is what this assignment is all about. In addition to giving you practice with C++ syntax and libraries, the assignment will guide you through the tools and approaches you can use to test and debug your code. By the time you've completed it, you'll be a lot more comfortable working in C++ and will be ready to start building larger projects!

This assignment is to be completed individually. Working in pairs/groups is not permitted.

Assignment parts

This assignment consists of two parts.

• Perfect Numbers

  is a fun warmup exercise involving number theory, algorithms, and optimization. It gives you a guided transition into C++, as well as the testing and debugging tools that we will be using in CS106B this quarter. You can get started on this one right away – and we recommend doing so! Aim to have this part of the assignment completed by Thursday, June 25. That way, you'll have time to get cracking on the bigger second part.

• Soundex Search

  is a complete program that demonstrates a nifty algorithm for matching and grouping names based on their pronunciation. This program uses C++ strings, console I/O, and the Vector class. Make sure that you have watched the lecture content on strings, Vector, and console programs (Wednesday and Thursday) before starting this part of the assignment. This part requires you to write a more substantial chunk of code, and getting a jump on it means you will have time to work through issues and reach out for help (using the Ed forum, LaIR, and instructor office hours) if you hit any snags. We recommend starting this part of the assignment no later than Friday, June 26. Aim to have this part of the assignment completed by Tuesday, June 30.

Getting started

We provide a ZIP of the starter project. Download the zip, extract the files, and open the project in Qt creator.

📦 Starter code

The two source files you will edit are:

• perfect.cpp
• soundex.cpp

Additionally, you will write short answers to some questions in short_answer.txt.

Before getting started writing code, we highly recommend reading the CS106B Style Guide. All of your assignment submissions this quarter will be graded on their coding style, and this guide contains the coding standards that make up our style rubric.

Helpful Resources

Here are some resources that you might find helpful for this assignment:

• A Guide to Testing Code in CS106B
• A couple of our section leaders have put together a wonderful guide to transitioning from Python to C++ that points out syntactical and functional differences between the two languages.
• Trip's Assignment 1 YEAH slides

Getting Help

As always, feel free to reach out to us if you have questions. You can contact us on Ed, email your section leader, or stop by the virtual LaIR (here is the schedule of help hours). You can find more information about how to get help at the LaIR here. As a reminder, try to visit the LaIR for coding debugging questions – however, if you cannot make it to the LaIR due to timezone issues, you can post on Ed to get help. However, you must use a private post if you are including code so that you are not posting your solutions for the whole class to see.

Submit

Before you call it done, run through our submission checklist to be sure all your ts are crossed and is dotted. Then upload your completed files for grading to the Paperless website.

Please submit only the files you edited; for this assignment, these files will be:

• perfect.cpp
• soundex.cpp
• short_answer.txt

You don't need to submit any of the other files in the project folder.

🏁 Submit to Paperless

Note: When submitting to Paperless, all due dates and submission times will be displayed in PDT across the website.

That's it; you're done! Congratulations on finishing your first CS106B assignment!
