Book excerpt: This book is designed for the way we learn. This text is intended for one year (or two-semester) course in "C Programming and Data Structures". This is a very useful guide for undergraduate and graduate engineering students. Its clear analytic explanations in simple language also make it suitable for study by polytechnic students. Beginners and professionals alike will benefit from the numerous examples and extensive exercises developed to guide readers through each concept. Step-by-step program code clarifies the concept usage and syntax of C language constructs and the underlying logic of their applications. Data structures are treated with algorithms, trace of the procedures and then programs. All data structures are illustrated with simple examples and diagrams. The concept of "learning by example" has been emphasized throughout the book. Every important feature of the language is illustrated in depth by a complete programming example. Wherever necessary, pictorial descriptions of concepts are included to facilitate better understanding. The common C programs for the C & Data Structures Laboratory practice appended at the end of the book is a new feature of this edition. Exercises are included at the end of each chapter. The exercises are divided in three parts: (i) multiple-choice questions which test the understanding of the fundamentals and are also useful for taking competitive tests, (ii) questions and answers to help the undergraduate students, and (iii) review questions and problems to enhance the comprehension of the subject. Questions from GATE in Computer Science and Engineering are included to support the students who will be taking GATE examination.
