This book assumes that you have some programming familiarity: you understand that a program is a collection of statements, the idea of a subroutine/function/macro, control statements such as “if” and looping constructs such as “while,” etc. However, you might have learned this in many places, such as programming with a macro language or working with a tool like Perl. As long as you’ve programmed to the point where you feel comfortable with the basic ideas of programming, you’ll be able to work through this book. Of course, the book will be easier for the C programmers and more so for the C++ programmers, but don’t count yourself out if you’re not experienced with those languages (but come willing to work hard; also, the multimedia CD that accompanies this book will bring you up to speed on the basic C syntax necessary to learn C#). I’ll be introducing the concepts of object-oriented programming (OOP) and C#’sbasic control mechanisms, so you’ll be exposed to those, and the first exercises will involve the basic control-flow statements. Although references will often be made to C and C++ language features, these are not intended to be insider comments, but instead to help all programmers put C# in perspective with those languages, from which, after all, C# is descended. I will attempt to make these references simple and to explain anything that I think a non- C/C++ programmer would not be familiar with. Learning
