Programs: Formal specification with Z

  • Mordechai Ben-Ari

Abstract

Suppose that you are asked to develop a program. The first thing that you must do is to write a specification of the program: what the program must do. Formally, a specification is a precondition and a postcondition, and the correctness of the program is defined relative to a specific precondition and postcondition. In practice, predicate calculus and number theory as we have presented them are inconvenient for writing specifications, and other notations have been devised.
