Title: Best I ever Used. Review: This mouse has the scroll ball, USB, and lazar pointer. I teach in large halls and it has no problem going the distance. Only con is you need a small screwdriver to change the battery. Other than that, It truly is one of a kind. I have used in it in over 100 computers and it always works.

Problem:

Title: A basic qualitative book for data structures but that is it. Review: I am currently taken a Data Structures course and this is the textbook being used at the university. The book gives basic qualitative understanding of data structures. The answers to the questions and excersizes at the end of each chapter are missing {at least provide the answers to odd ones like other texts}. Standard Templates are given however, Microsoft Visual C++ products do no compile examples without some tweaking. This book seems to be geared to the Borland compiler. The are errors in the coding and text explainations. The authur uses the same name for functions and iterators in the examples which makes learning a little more difficult. I using another book to augment my learning. Is this product review negative?
