Example Input: Substandard Text or Reference on RF Electronics. . This is a required text for a graduate level RF electronics course I am taking. I am very disappointed with this text. There are multiple mistakes and misprints throughout. It seems that the book was proofed by someone who is not familiar with electronic symbology and notation. There are many instances where inconsistant notation will be used within a single example problem! The author is very short on many subjects and longwinded on others. This book makes for a confusing and frustrating read despite the distinguished IEEE brand on the cover. My professor even commented on the sloppyness of the author. I have had to buy additional books to suppliment my studies. This is not a good reference or text book....Coming from someone who has read multiple technical text books...Beware of this one
Example Output: NEG

Example Input: Awful book on its own for complete beginner . I wanted to teach my son to program and chose VB and this book. This book really "looks" great but I'm not impressed by the content. So much so that it compelled me to write my first ever book review. The introduction "Who Is This Book For?" gives a sense that this book can get people into programming. I would be amazed however if anyone not familiar with programming will get past Chapter 1 without being frightened by the whole prospect of programming. Chapter 1 initially jumps into some Microsoft marketing of .Net which really adds nothing but confuses the readers by having to deal with line after line of computer jargon. Then the chapter gives a horrible overview of Object Orientation which again doesn't help later. I feel the whole book is like the first chapter. Doesn't give you some of the basics but rambles about more complex stuff you don't need between some hands on practical stuff. I actually thought the first example was really poor also. I am of the opinion that someone typing something in themselves and seeing it work should be rewarding. The example however was hard for a novice as it had long lines of comments and the line to print the variables was a minefield of quotes and symbols making it pretty likely that a beginner would do a typo. The title of the book is "Build a Program Now!". This the book does and given how complex setting up an environment it is helpful. But I've slammed the rating of this book because this could have covered with a lot less pages and maybe substitute some of the drivel with a little about the syntax of VB or even some explanation of the example code. DON'T buy this book if you think it will teach you anything about computing or programming. DO buy this book if you have some other teaching reference for Visual Basic and want something that will help you setup your build environment. Also comes with a VB Express CD so you don't have to downloaded it.
Example Output: NEG
