In programming language theory, semantics is the rigorous mathematical study of the meaning of programming languages. Semantics assigns computational meaning to valid strings in a programming language syntax. It is closely related to, and often crosses over with, the semantics of mathematical proofs.

18 de mar. de 2024 · Learn how lexicon, syntax, and semantics are the core components of any programming language. Lexicon defines the words, syntax defines the rules, and semantics defines the meaning of the source code.
Learn how to formally define the meaning of programs using operational, denotational, and axiomatic semantics. See examples of a simple arithmetic language with assignment and small-step operational semantics.
Dynamic semantics: What is the meaning of a given arithmetic expression? Syntax. Languages begin with primitives, or objects that represent atomic units of meaning. Arithmetic has only one primitive, numbers, while most programming languages have many primitives like characters, booleans, functions, and so on.
