When to Use a Citation

Writing code is similar to writing a paper: when you use or adapt someone else's work in your own project, you must give credit to that source. 

See below for examples on how to properly cite code and images in your own work.

How to Cite: Source Code

Within your code, provide the URL of the original source and the date you found the code. If you adapted the code in your work, be sure to also indicate that ("Code adapted from" or "Based on").

Example:

// Code adapted from MSDN example:
// http://msdn.microsoft.com/en-us/library/ms680578(VS.85).aspx

How to Cite: Images Found Online

Note: For Google Images, navigate to original website to attempt to locate author, title and date.  If the image does not have an identifiable author, date, or title, use the rules for citing sources with missing elements.
