  2. Syntax and semantics of logic programming - Wikipedia

    en.wikipedia.org/wiki/Syntax_and_semantics_of...

    This article describes the syntax and semantics of the purely declarative subset of these languages. Confusingly, the name "logic programming" also refers to a specific programming language that roughly corresponds to the declarative subset of Prolog. Unfortunately, the term must be used in both senses in this article.

  3. Programming language specification - Wikipedia

    en.wikipedia.org/wiki/Programming_language...

    A programming language specification can take several forms, including the following: An explicit definition of the syntax and semantics of the language. While syntax is commonly specified using a formal grammar, semantic definitions may be written in natural language (e.g., the approach taken for the C language), or a formal semantics (e.g., the Standard ML [3] and Scheme [4] specifications).

  4. Comparison of programming languages (syntax) - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_programming...

    With respect to a language definition, the syntax of Comments can be classified many ways, including: Line vs. block – a line comment starts with a delimiter and continues to the end of the line (newline marker) whereas a block comment starts with one delimiter and ends with another and can cross lines

  5. Comparison of programming languages - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_programming...

    Like natural languages, programming languages follow rules for syntax and semantics. There are thousands of programming languages [ 1 ] and new ones are created every year. Few languages ever become sufficiently popular that they are used by more than a few people, but professional programmers may use dozens of languages in a career.

  6. Syntax (logic) - Wikipedia

    en.wikipedia.org/wiki/Syntax_(logic)

    Syntax is usually associated with the rules (or grammar) governing the composition of texts in a formal language that constitute the well-formed formulas of a formal system. In computer science, the term syntax refers to the rules governing the composition of well-formed expressions in a programming language. As in mathematical logic, it is ...

  7. Semantics (computer science) - Wikipedia

    en.wikipedia.org/wiki/Semantics_(computer_science)

    In programming language theory, semantics is the rigorous mathematical study of the meaning of programming languages. [1] 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.

  8. Semantic gap - Wikipedia

    en.wikipedia.org/wiki/Semantic_gap

    The semantic gap characterizes the difference between two descriptions of an object by different linguistic representations, for instance languages or symbols. According to Andreas M. Hein, the semantic gap can be defined as "the difference in meaning between constructs formed within different representation systems". [ 1 ]

  9. Comparison of Pascal and C - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Pascal_and_C

    C allows using bitwise operators to perform Boolean operations. Care must be taken because the semantics are different when operands make use of more than one bit to represent a value. Pascal has another more abstract, high-level method of dealing with bitwise data, sets. Sets allow the programmer to set, clear, intersect, and unite bitwise ...
