I just want some feedback/advice... I hope to be someday be a C 'guru' and right now, my C is quite alright though nothing great. What books do u recommend reading to advance your C to the next level? I would consider myself to be at the intermedite level. I program using Unix platform. An important requirement would be the topics in the book is helpful to real life work requirements. After all, what use is it if I am an expert in some hardly used parts of C such as recursive functions.. ?
