Semantics of a programming language is the definition of themeaning of any program that is syntactically valid. intuitive idea of programming meaning: “whatever happens in a (real or model) computer when the program is executed.”. n A precise characterization of this idea is called operational semantics.

Semantics. The investigation of interpretations of a logical calculus (a formal axiomatic theory), of the study of the sense and meaning of constructions in formal language theory, and of the methods of understanding its logical connectives and formulas. Semantics studies the precise description and definition of such concepts as "truth" ,

The goal of axiomatic semantics is to provide axioms and proof rules that capture the intended meaning of each command in a programming language. These rules are constructed so that a specification for a given command can be deduced, thereby proving the partial correctness of.

In axiomatic semantics, we may often deal with erroneous cases just by making. An axiomatic description of a language, it was said above, is a theory for that.

The defined structure may be seen as circular in two respects: On the one hand it is the precondition for the understanding of its own syntactic and semantic. for the whole language. Thus the.

Axiomatic semantics is commonly associated with proving a program to be correct using a purely static analysis of the text of the program. This static approach is in clear contrast to the dynamic approach, which tests a program by focusing on how the values of variables change as a program executes.
