Although many books are available in the market for Jawaharlal Nehru Technological University (JNTU), first year B. Tech. students, but this book has an edge over others. Following are the highlights, which have silently made it the best book of the market: This book is written exactly as per syllabus. Syllabus specifies three main streams for learning. One stream suggests topics for computer learning. Second stream suggests topics for C programming and third stream suggests types of data structures that are supported in C language. This book is a single-window-solution for all the three streams. It covers all the three aspects mentioned in the syllabus. Students need not purchase separate books for each stream. This book will be just sufficient for them. The language of the book and the style of writing is one of the prime highlights. The language of the book is easy, no jargons are used and all the technical words are well explained before they are introduced. Thus no confusion of any kind prevails in the book. Readers get best returns for their time spent in this book. C language portion of the book is not only content rich but is program rich also. After explaining a topic or command, many programs are introduced, there itself, so as to explain the practical aspects of the topic. Most of the books directly write the program, without explaining the problem, for which the program is written. But in this book, each problem is explained in clear words, before the program is written. This approach helps in understanding the logic of the following program, clearly. For all those programs, which require strategic planning before they are written, a special section, named "Program Strategy" has been added, before the program. This section explains the complete framework, on which the following program will be built. All the programs of this book are working programs. We have tried and tested them and found them working perfectly all right. Readers can directly type these programs on their computer and work with them. This will make the learning fast. Wherever necessary, results of the program are also included after the program. This approach helps in understanding the dynamics of the program.
