Textbook in PDF format The study of data structures and algorithms is fundamental to computer science and engineering. The primary goal of this book is to promote object oriented design using C++ and to illustrate the use of emerging object oriented design patterns. The secondary goal of this book is to present mathematical concepts for analyzing the various aspects of data structure algorithms and applications relevant to the present day needs of the students studying Computer Science and Engineering both in the undergraduate and post graduate course of studies in various universities in India. This book presents the various data structures and algorithms as complete C++ program fragments
