The C answer book 2nd ed.

The new edition of Kernighan and Richie's best-selling text offers the same outstanding quality of presentation that made its first edition the model of all computer programming texts to date. The authors describe the features that have entered the language since the publication of the first edition, including structure assignment, enumeration, void type, and stronger type checking. In addition, the authors have improved the exposition of critical features, such as pointers, that are central to C programming. They have refined the original examples, and have added new examples in several chapters. There is also new material on organizing programs into multiple source files and on variable-lenght argument lists.
