Annotation 

We provide a verification technique for a class of programs working on \emph{integer
arrays} of finite, but not a priori bounded length. We use the logic of integer arrays \textbf{SIL} \cite{lpar08} to
specify pre and postconditions of programs and their parts. Effects of nonlooping parts of code are computed
syntactically on the level of \textbf{SIL}. Loop preconditions derived during the computation in \textbf{SIL} are
converted into counter automata (CA). Loops are automatically translatedpurely on the syntactical levelto
transducers. Precondition CA and transducers are composed, and the composition overapproximated by flat automata with
difference bound constraints, which are next converted back into \textbf{SIL} formulae, thus inferring postconditions
of the loops. Finally, validity of postconditions specified by the user in \textbf{SIL} may be checked as entailment is
decidable for \textbf{SIL}.
