With the aim of the verification of programs in the C-light language [1], its kernel C-kernel is separated, and an axiomatic semantics for it is suggested. A theorem on soundness of the axiomatic semantics of C-kernel with respect to its operational semantics is proved. The C-light language is used as an input language of the program verification system,(More)
In the paper, a new three-level approach to the verification of sequential object-oriented programs is presented. It is applied to an expressive subset C#-light of the C# language, which includes all basic sequential constructs of the latter. At the first stage, the C#-light language is translated into the intermediate C#-kernel language. At the second(More)
The C-light language is described, which is a representative subset of C. C-light permits deterministic expressions, limited use of switch and goto statements, and, instead of library functions for work with dynamic memory, includes C++ statements new and delete. A survey of structured operational semantics of the C-light language in Plotkin's style is(More)
There are two major formalisms that are developed around concepts. The first one is Formal Concept Analysis (FCA) by R. Wille and B. Ganter. Roughly speaking, FCA is an extension of algebraic Lattice Theory for knowledge representation. The second formalism, Description Logic (DL), goes back to the universal terminological logic by P.F. Patel-Schneider. It(More)
Verification of imperative programs in the sense of Floyd-Hoare is an approach to proving correctness of programs annotated by preconditions, postconditions, and loop invariants. It is based on generation of correctness conditions. In the structured deterministic case, the problem of generation of correctness conditions seems trivial, since it is solved by(More)
An extendable multilanguage analysis and verification system SPECTRUM is presented; this system is being developed in the framework of the project SPECTRUM. The prospects of the application of this system are demonstrated, as exemplified by the verification of C programs. The project SPECTRUM is aimed at the creation of a new integrated approach to the(More)
The mixed axiomatic semantics of the C-kernel language is described. This language is the kernel of a representative subset which is called C-light. Such semantics makes possible for the verification conditions to be simplified in many cases. The semantics is the basis of the verification conditions generator for C-kernel programs. An example illustrating(More)
Development of formal programming language specifications is an important problem of theoretical and practical programming. The paper presents operational ontological approach to formal specification of programming languages. It defines formalism for introduction of operational ontological semantics of programming languages: ontological transition systems,(More)
