"This book is a tutorial. Its aim is to teach C to a beginner, but with
enough of the details so as not be outgrown as the years go by. It presumes
that you have some previous aquaintance with programming — you need to
know what a variable is and what a function is — but you do not need much
experience. It is not essential to follow the order of the chapters rigorously,
but if you are a beginner to C it is recommended."
