Abstract

C is a well known and very popular general purpose programming language which represents, together with its descendants, a strong and indisputable status quo in the current software industry. Its semantics is informally defined in the ISO/IEC 9899:1990 standard [1] using natural language. This causes a number of ambiguities and problems of interpretation, clearly manifested in numerous discussions taking place in the newsgroup comp. std. c. It is worthwhile noticing that members of the standardization committee and other distinguished researchers participating in the discussions often give contradictory answers when asked about the intended semantics of surprisingly small programs, and that their answers are usually based on different possible interpretations of the standard. With all this in mind, the necessity for a formal description of the semantics of C becomes apparent. Such a description would serve as a precise standard for compiler implementation and would provide a basis for reasoning about properties of C programs.
