APCS Study Guide APCS has a guide that helps you use VirtualBox to install an environment on your computer that you can use to write and run the programs shown here in the APCS section. You can also use wsl on windows or the native shell on a mac. But since it provides such a wonderful standard environment you may wish to go with the APCS guide anyways.

Coding Basics TO a large extent this will depend on what language is introduced first. At times I have used CBM BASIC, PHP, Python or other languages to teach. The language itself is not so important because all the basic concepts are going to be the same. However, out of all the major languages, Python has the least amount of things you need to learn before you can look at a program. Python is not my first choice, But it is great for a basic programming course. However, I don't think that it …

Basics II: Random Numbers The second thing I taught the class was random numbers. What is the answer? The students were amazed when the number was different each time! Then I said, let's combine the two ideas, and we did this: This program printed a name, of their friend, or, the student number. It was the focus of the entire class, to let them play with this idea.

Basics III: Arrays and Lists In this class we will explore the idea of adding words to a list and then sorting them. In part II we will turn this into a game where the student can pick a number to move a word to the top of the list and then when the list is sorted they can 'win'. Well, here is the first thing:

Dice Class The “Class Dice” I usually write is a utility class, and as such it is a static class. Therefore this lesson requires previous instruction in basic classes and object oriented programming. Students should be familiar with encapsulating objects as classes as well as aspects of (game) programming such as save files, windows, game engines, etc.

J1-3 Loops In the study of programming languages, we have the concept of program control flow, which always operates in ONE direction. This means the CPU will pull an instruction, execute it, then increment the IP (instruction pointer) or PIC (program instruction counter), etc. and then pull the next instruction.

JavaScript Terminal v3 When I began to write NetWhack, I decided that the game would start out as a terminal emulator, and then the game would rely on the terminal emulator side of the software as if it were a game engine. I liked this 'old school' environment because it was nostalgic for me. It is how I learned to code, way back in the day, so I thought it would be a fun little project to write a interface that would look like a Commodore or a PC or some kind of monochrome terminal.
