I quote from the publishers web site:
"The ever-increasing dependence of our lives and livelihoods on the
correct functioning of computer software means that logic and program
correctness are core elements of all good computer science degrees.
This book presents both these topics in one self-contained text.
The focus of the book is on "correct-by-construction" program design --
the discipline of calculating programs from their specifications.
Modern, calculational logic is introduced in combination with key
program construction principles, such as the assignment axiom, loop
invariants and bound functions. This material is intertwined with
motivational discussion, programming examples and challenging
problem-solving exercises, bringing the book alive for its intended
audience, undergraduates in computer science and mathematics, as well
as professional programmers wishing to further develop their
The book covers the elements of logic and program correctness that form
the foundations of further study --- the logical connectives and their
algebraic properties, induction, quantifiers and program construction
rules. Substantial examples of program construction are included. Many
exercises are provided, all with detailed solutions. "
