# 1.2. Resources Online¶

This book is designed for Comp 170 at Loyola University, Chicago. The materials are available to all on the web. Here are some important web links:

• The course example file, is the essential resource to download and unzip onto your machine. The zip file and the folder it unzips to have a long name, introcs-csharp-master-examples. We suggest you rename the unzipped folder examples to match later references.

Computer programs are designed to run on a computer and solve problems. Though the initial problems will be tiny and often silly, they will serve as learning tools to prepare for substantive problems.

• https://luc.box.com/CSharpVideos is a box.com folder containing all the videos. The numbers at the beginning of the titles are chapter and section numbers from the text. These make it easy to sequence the videos, even though there is not an automatic playlist. The listing in box.com takes up several pages. These box.com videos may be

• streamed, including at full size (though generally after an initial delay),
• the whole gigabyte folder can be downloaded at once to play later on your machine. (This is a choice on the menu under the page’s Folder Options.)

There is a mixture of new high-def videos and older lower resolution 800x600 pixel videos. In that folder see 00README.html, https://luc.box.com/s/2lqak4pbsdcyw08ds3ia, for a description of the differences between the old videos and the latest update of the online book.

For those who learn best with spoken words combined with written words, the videos should be a good start. Even if you use a video for a section, you are encouraged to review the written text afterward. Then be aware of the written version for quick reference. The written text may include extra details and exercises, and it will have the latest revisions.

In various formats, be aware of these helpful features:

• We have picked out particularly important words, phrases, and symbols, and put them in our index, which is accessible from the banner of each web page. The banner stays visible if the window is big enough, and if the window is smaller, the baner only appears at the beginning of the page with a dropdown menu for most of the options.
• In a web version on our website, you can use the Search option to look for words, in general. The search link is also accessible from the web page banner. This does not work on a downloaded local html copy.
• The web version and pdf versions display mathematical formulas prettily. If you use the local html version when not connected to the internet, you see only the LaTex encoded source for formulas. While offline reading sections with math formulas, we suggest using the pdf version.
