Written by the originator of the USENET C FAQ, this book addresses the real-world problems on C programming that are asked, again and again, on the "comp.lang.c" newsgroup. The book is aimed at C programmers who need quick, concise answers to the stubborn questions which invariably arise when programming in C. It provides accurate answers, insightful explanations, and extensive code examples.
The book (if an assortment of unrelated Q&As could be called such) is an excellent way to test and enhance your knowledge of the C language. I have many years of experience writing C code, and while most answers were obvious to me, there were some that completely threw me out of my comfort zone and provided ample food for thought. I wholeheartedly recommend the book (or the free online version of it) to any C programmer with some prior experience who wants to know all the edge cases and "gotchas" of the language that are so frequently swept under the rug by many C programmers and book writers.
I'm absolutely shocked how often I still must quote comp.lang.c FAQ entries at supposedly "skilled" C programmers. This is a more complete treatment of the classic Eskimo version of the FAQ than is available online; watch out for some slightly obsolete elements (note that C99 is not addressed, but that's rarely important).
An absolute must-have for any C programmer. If you find yourself tripping on C syntax (and so many of us do, regardless of experience), Summit has very likely addressed the issue in this book.
