CS 1: Lecture 21 – Loops, Part 3

Dear students, We explore more examples of loops today. Because we are, in fact, stuck in a loop. There’s no way out of this. Write a program that prompts a user for a file. Report how many bytes it occupies on disk. If a bad file is entered, repeat the prompt until the user gets […]

CS 148: Lab 7 – Conditionals and Loops

Welcome to lab 7! If you have checkpoints from the last lab to show your instructor or TA, do so immediately. No credit will be given if you have not already completed the work, nor will credit be given after the first 10 minutes of this lab. In this lab, we’ll explore conditional statements, which […]

CS 1: Lecture 20 – Loops, Part 2

Dear students, Three big ideas will consume the rest of our semester: loops, arrays, and objects. Nothing we’ve discussed so far will go away. We will be spending our days seeing applications of these ideas. Like today. Our entire time will be spent writing some applications that use loops. Write a program that counts the […]

CS 1: Homework 4 – Proportable – due before November 8

See the PDF. Eventually, you’ll need to Team / Pull… from the template repository to get the SpecChecker, which is almost finished.

CS 396: Meeting 7 – Epic

Dear students, Today we welcome Zach Forster from Epic. Before that, Zach paid the bills by grading CS 163 homeworks. I pleaded and pleaded with Zach to attend graduate school. We went to the University of Minnesota once to attend a graduate school open house. I failed to enlist him. He said that he wanted […]

CS 1: Lecture 19 – Loops

Dear students, I write from California, with its red tile roofs and bank-breaking housing. We will not be meeting for lecture while I am presenting at the FabLearn 2017 conference, but I have a few videos for you to watch. Just as we saw how if statements can cause our CPU to jump ahead to […]

CS 145: Lab 6 – Conditionals

Welcome to lab 6! If you have checkpoints from the last lab to show your instructor or TA, do so immediately. No credit will be given if you have not already completed the work, nor will credit be given after the first 10 minutes of this lab. In this lab, we’ll explore conditional statements, which […]

CS 148: Lab 6 – Logical Expressions

Welcome to lab 6! If you have checkpoints from the last lab to show your instructor or TA, do so immediately. No credit will be given if you have not already completed the work, nor will credit be given after the first 10 minutes of this lab. In this lab, we’ll explore the logical operators […]

CS 1: Lecture 18 – If Bifurcations and Ladders

Dear students, Last time we saw how we could introduce extra little diversions or sidesteps into our code. Some bit of code needs to get executed under certain conditions, so we embed it in an if. In other situations, we actually want to choose between two competing bits of code. I call this pattern a […]

CS 396: Meeting 6 – Jamf

Dear students, Today we welcome a team of panelists from Jamf to discover the software engineering process. These folks have been welcome partners. During my first summer in Eau Claire, I was looking to gain some experience with iOS, so they hired me on as Dr. Intern. They’ve hired an overwhelming number of our students. […]
