Once you get addicted to solving questions in this book, discovering shortcuts in C and the traps usually in university exams, you won't leave a question untouched. It will improve your knowledge of C tremendously if you are new to C. I don't know if there is a solution manual to this book yet, but you might want to run behind professors to get your doubts cleared, I know I did.
A great one.. Totally not for beginners.. It tests the rare and weired practices and traps.. I enjoyed it very much and I still repeat reviewing its tricks, so that I may take care of them later. Many of the mentioned tricks appear in companies exams :D .
