In the first edition of this book, I decided to assume that someone else had taught you C and that you have at least a reading level of comfort with it. My primary focus was on simplifying what I found difficult: the C++ language. In this edition I have added a chapter that is a rapid introduction to C, along with the Thinking in C seminar-on-CD, but I am still assuming that you already have some kind of programming experience. In addition, just as you learn many new words intuitively by seeing them in context in a novel, it’s possible to learn a great deal about C from the context in which it is used in the rest of the book.
