It is very basic book only for low IQ level students . This book dont have good problems for practice. I would not suggest you to read this book because I think it will be a waste of time. You must have known all things before there is nothing new. If u are beginner in programming than you can go through this book and it might end up helping you other wise I do not find any good content in it. Although it is written by indian author it’s language is easy to understand. It’s cost is also I think 70 to100 rupees high. There is no answers to the book’s execise.
