Formal specification techniques for engineering modular C programs

Software is difficult to develop, maintain, and reuse. Two contributing factors to this difficulty are the lack of modular design and good program documentation. The lack of modular design in software makes software changes more difficult to implement. The lack of good program documentation makes programs more difficult to understand and to maintain. Formal Specification Techniques for Engineering Modular C Programs describes a novel approach to promote program modularity. This book presents a formal specification language that promotes software modularity through the use of abstract data types even though the underlying programming language does not have such support. This language is structured to allow useful information to be extracted from a specification and used to perform some consistency checks between the specification and its implementation. Formal Specification Techniques for Engineering Modular C Programs also describes a specification-driven software reengineering process model for improving existing programs. The aim of this process is to make existing programs easier to maintain and reuse while keeping their essential functionalities unchanged. Formal Specification Techniques for Engineering Modular C Programs is suitable as a secondary text for graduate level courses in software engineering, and as a reference for researchers and practitioners in industry.
