Description

Tutorial describing queue methods including enqueue, dequeue, empty, and front. The queue is implemented using a linked representation. Presentation is as a "slideshow," as in a presentation for class. Standard "video" controls control the slideshow, including the ability to go backward. Users can turn on automated slide advance ("kiosk" mode) or control the pacing manually.

Evaluation

Clear presentation. Students should be able to understand it. A nice feature is including information about "common mistakes". Each topic is explained through simple pseudocode and simple animation. The fluid animation helps make clear how nodes are inserted or deleted into the linked list, and the advanced pointer manipulation involved with each method. Color is used sparingly in this AV: mostly black and white, with blue used to highlight the main topics. Red is used to highlight common student mistakes, which was a useful feature, especially for someone who is new to programming.

What could have been more useful with this AV is if it showcased the queue in multiple ways, such as in the form of the circular queue or at the memory level, in which the viewer would be able to see the memory manipulation that is involved in implemented the member functions of the queue.

Usage Notes

For detailed instructions on how to install Animal and run Animal AVs, see: http://www.algoanim.info/Animal2/?q=node/290. Once you have installed the Animal .jar file and downloaded/unpacked the .zip file of Animal animations, you are now ready to run Animal. Run the .jar file to start Animal. Then go to the "Open" menu item, and browse to where you put the animal animations you got in the .zip file. Pick this AV from the list. You can then step through the animation, or use "kiosk mode" to have the steps fed to you at a constant pace.
