Programming Concepts

  1. Watch thevideo 2.2.1 Sequence, Selection and Iteration - Revise GCSE Computer Science.

    Goal: You can explain what sequence, selection (condition) and iteration (loop) are, and recognize them in each of the processes in Exercise 3.

Package manager & terminal

We will use a package manager to install software in this course . A package manager is similar to an app store.

We will use winget in Windows and Homebrew in MacOS. Most Linux distributions have their own package manager.

Winget is built-in in Windows, but Homebrew must be installed on MacOS.

Opening a terminal

We will use a terminal to install software. So you should now how to open a terminal.

Windows
MacOS
Linux

  1. Press the Windows key

  2. Type cmd. A black terminal window should pop up.

Homebrew installation

  1. Open a terminal.

  2. Copy the command for installing Homebrew from their website.

  3. Paste the copied command into the terminal you opened and then press Enter.

VSCodium

We will use VSCodium as coding tool[1]. Use your terminal to install VSCodium:

Windows
MacOs
Linux
winget install vscodium

If you run into problems, take a look at https://vscodium.com/#install.

We will install additional tools later.

Footnotes

  1. VSCodium is based on Visual Studio Code (VS Code).We use VSCodium instead of VS Code, because it does not recommend installing extensions like Copilot and chat assistance as default. In turn, some Microsoft extensions likeCopilot is only available for VS Code.

    This deliberate choice is to avoid distractions and to focus on the learning goals we want to reach.
