There are three main approaches to formally specify the semantics of programming languages: operational semantics: describes how a program would execute on an abstract machine; denotational semantics: models programs as mathematical functions;
Semantics. Introduction. Language implementors. n Understand how all the constructs of the language are form and their intended effect when executed. Language users. n Determine how to encode a possible solution of a problem (program) using the reference manual of the programming language.
The aim of this course is to introduce the structural, operational approach to program-ming language semantics. It will show how to specify the meaning of typical programming language constructs, in the context of language design, and how to reason formally about semantic properties of programs. Lectures •Introduction. Transition systems.
13 lut 2024 · The syntax of a programming language is the set of rules governing the formation of expressions in the language. The semantics of a programming language is the meaning of those expressions. There are several forms of language semantics. Axiomatic semantics is a set of ax-iomatic truths in a programming language. Denotational semantics involves ...

The aim of the course is to introduce the structural, operational approach to programming language semantics. (An alternative, more mathematical approach and its relation to operational semantics, is introduced in the Part II course on Denotational Semantics.)
9 wrz 2004 · In this lecture we illustrate the basic concepts underlying the static and dynamic semantics of a programming language on a very simple example: the language of arithmetic expression augmented by variables and defini-tions. The static and dynamic semantics are properties of the abstract syntax (terms) rather than the concrete syntax (strings).
