There are lots of concepts in C programming that are not easily available either on the internet or in textbooks. We tried our best to deliver concepts through explanations of C questions. Each and every question has a concept behind it. These concepts are damn important for students who are planning to appear for any multinational IT company job. Every company needs programmers/coders who are good with logic and sound in fundamentals. This book is proved a diamond for genuine C programmers and for serious job seekers.

The book contains more than 500 C programming questions. You only need a maximum of 25 days to complete the book. The guidelines for reading this book are given below. We recommend you to follow these guidelines and try to finish the book before the deadline. At the end of each group, some other important interview questions are present. Try to write programs and execute .

If you are having a lack of time and good programming skills then try to write at least an algorithm or pseudocode for them. All C codes are compiled and executed with gcc 4.8.2 compiler driver running on a Linux system with kernel 3.13.0-32-generic under ubuntu-14.04 32-bit Operating system. We also recommend you to execute the given codes in your system for better understanding and let us know if there is any correction. Organization of the Book The chapter-1 "A touch to C" describes conceptual understanding about C programs. It is highly recommendable to the readers to go through this chapter before proceeding further. After this chapter, the book is divided into 7 groups, each group contains around 60 C programming questions with explanations and other important interview questions.

After completing all the groups, there are more than 100 questions given in 5 sample papers with solutions for your practice. The book overall contains more than 600 interview questions. Prerequisite A very basic understanding of theoretical C concepts is required for reading this book. Guidelines For Reading the Book
