This book is intended to be a reference manual and hence a precise
description of the C language.
It also attempts to remain readable by ordinary humans.
When new concepts are introduced, examples are given to provide
clarity.

Since C is a programming language that is supposed to aid programmers
trying to write portable programs, this book points out those areas
of the language that may vary from one system to another.
Where possible, the probable behavior of other C compilers is
mentioned.
