The study of Data Structures through C++ is fundamental to computer science and engineering. This is essential for us to develop computer programs that utilize computer resources in an effective manner. The practical orientation of this book is due, so my tendency is to design things from an engineering point of view, always balancing the ideals of theory with the reality of practice. This book is written primarily for intermediate-level C++ programmers. The book has been designed to be useful to both those programmers with little C++ experience as well as those at an advanced level. This is accomplished by approaching each subject at a basic level, providing simple techniques, and then progressing to more exotic and advanced techniques. Thus, if you are at the starting point of the C++ learning curve, you can work with the early parts of each chapter. As you become more proficient, you can tackle the more advanced sections. If you're a more experienced programmer, you can use the first parts of each chapter as refresher material, and then quickly move on to the advanced material.
