Welcome to the GitHub repository for the FutureLearn MOOC "Defensive programming and debugging".

Here you will find source code that you can use for the quizzes. It will grow over time since we will add example solutions at the end of the week, as well as the material for the coming week. So you should keep an eye on it.

You have three options to use this repository,

1. Simply download the individual files as you need them.
2. Clone the repository: straightforward, but you should make copies of files if you want to modify them.
3. Fork the repository: best approach if you are familiar with the procedure.

This is the simplest approach if you are not familiar with version control systems.

1. Navigate to the file you want to download.
2. Click on the Raw button, your browser window will show the source code only.
3. Use Save As to save the file to your computer.

The drawback is that you will not get updates automatically in case we add or fix material.

You can clone this repository using the following command:

$ git clone https://github.com/gjbex/DPD

This will create a directory DPD that contains your clone of the repository that you can use to work in. When material is added to the repository, you can update the repository using:

$ cd DPD
$ git pull origin master

Note that if you modified files in the repository, the pull will fail. Hence first copy files before you modify them. Copies can reside in your repository directory, so you can simply work there.

This is definitely the best approach but you need to be familiar with the procedure. If you use this alternative, we assume you know what you are doing.
