Implementation of data structure is the basic requirement of any C/C++ program. This book covers significant material on design and implementation of linear as well as nonlinear data structures. Rather, it is a study of data structures organized by concepts and programs. This book is divided into small chapters so that every topic can be understood properly. The topics with each chapter are in proper sequence to ensure smoothness of the subject. Data structures and its applications are explained with help examples as well as programs.
