Data Structures and Object-Oriented Programming with C++ has been specifically designed and written to meet the requirements of engineering students. This is a core subject in the curriculum of all Computer Science programs. The aim of this book is to help students develop programming and analytical skills simultaneously such that they are able to design programs with maximum efficiency. The use of C language has been incorporated in the book to permit the execution of basic data structures in a variety of ways. This book also provides an in-depth coverage of object-oriented concepts, such as encapsulation, abstraction, inheritance, polymorphism, message passing and dynamic binding, templates, exception handling, streams and standard template library(STL) in C++.
